我在这里问这个是因为我在网络上的任何地方都找不到解决方案。
KMail 目前可以接收我的电子邮件，但不会发送任何邮件（发送到邮件列表或常规地址）
它给我的错误是：
“5.7.1 由于信封和标头发件人不匹配而被拒绝。”
我该如何解决？
使用mail(from mailutils)，发送包含 html 消息和附件的电子邮件的唯一方法是包含来自文件的消息，如下所示：
mail \
--content-type=text/csv --attach=/tmp/filename.csv \
-a "From: [email protected]" \
-s "An HTML Email with Attachment, Yay!" \
--content-type=text/html \
[email protected] < /tmp/filename.txt
然而，我需要做的是filename.txt从远程服务器获取最后一个文件（其中包含 html 的文件）。
我可以通过 ssh 进入远程服务器，没有任何问题，例如，
但是当我尝试将mail命令指向远程服务器上的那个位置时，我得到“没有这样的文件或目录”，但毫无疑问该文件在那里。
mail \
--content-type=text/csv --attach=/tmp/filename.csv \
-a "From: [email protected]" \
-s "An HTML Email with Attachment, Yay!" \
--content-type=text/html \
[email protected] < ssh [email protected]:/tmp/filename.txt
我已经尝试了所有我能想到的 backtics 和管道组合，但我无法让它发挥作用。
顺便说一句，是的，当本地服务器上的用户通过 ssh 以远程服务器上的用户身份登录时，可以查看、打开和编辑远程文件。
所以
ssh [email protected]
nano /tmp/filename.txt
工作正常。
有任何想法吗？
目前我只是在发送电子邮件之前将文件复制到另一台服务器，但我宁愿不必这样做。更喜欢单线。
我在两台服务器上都使用 Ubuntu 18.04。将 postfix 与 mailutils 一起使用。
我正在设置我的电脑，我想要设置的所有东西都已完成，但我遇到的问题是我的电子邮件是由 Tutanota 处理的，它是专有的，不能添加到通用电子邮件客户端。有一个桌面客户端，但它是一个 appimage，我一生都无法弄清楚如何将其设置为默认值。当我访问 webmail 时，它会立即提示我是否要将其用作我的默认邮件，如果我无法使其正常工作，我会这样做。我找到了这个线程：
我试图将那里的一些信息应用于我的问题，但我怀疑我有一个 appimage 而不是实际安装的应用程序这一事实可能是一个无法解释的混淆因素。当我尝试在 appimage 上运行 gedit 时，文本编辑需要几分钟才能打开并显示许多未加载的字符和红色双零，老实说，我真的被吓到了。我试图按照某人的建议进一步编辑 mimeapps.list ，它不在我系统上的那个目录中，但我确实找到了 mimeinfo.cache ，其中包含建议的行，所以我按照指示进行了编辑，但无济于事。
我还发现了这个线程：
虽然我能够使用那里的信息使我能够使用我的桌面客户端打开保存的原始电子邮件，但我仍然无法将其添加为我的默认邮件应用程序。
我觉得我错过了什么。有人对如何使用 Tutanota 桌面客户端 appimage 作为 Ubuntu 中的默认邮件应用程序有任何想法吗？
更新：我测试了几个不同版本的 Thunderbird，因为我知道这是 Ubuntu 的默认邮件客户端。正如预期的那样，appimage 版本没有显示为默认电子邮件客户端的选项，但从网站手动下载也没有，我能够按预期打开和使用该应用程序。系统在设置中实际识别为邮件客户端的唯一 Thunderbird 版本是从 Ubuntu Software 下载的那个。我仍然不确定有什么区别，所以如果有人知道，请告诉我。我想我可能只需要坚持使用 webmail 作为我的默认“电子邮件客户端”，如果它只能识别来自 Ubuntu Software 的应用程序。
搜索只能找到 2013 年或 2014 年左右的旧结果。Linux 上 Facebook 通知的状态如何？有新消息到达时通知我的应用程序吗？欢迎任何形式的通知，如果不是声音，至少面板栏上的闪光灯，任何东西。（这里是Xubuntu 16.04.3）
正如我的标题所说，我对 nullmailer 的配置有一些问题。基本上我一直在关注这个网站。
我已经在 Mailchimp 上创建了一个帐户 - 我已经成功发送了测试邮件。在我的机器上我安装了 Nullmailer：
然后我配置了遥控器：
smtp.mandrillapp.com smtp --port=587 --starttls [email protected] --pass=boo
我已经设置了adminaddr
cat /etc/nullmailer/adminaddr
[email protected]
默认域保持为空
这就是我的 mail.log 的样子：

但我真的不知道从这一点出发。有任何想法吗？谢谢。
我的网络提供商最近从 Ubuntu 14.04 更改为 18.04。这破坏了我用来发送没有正文但带有附件的电子邮件的自动脚本。我缩短了下面的代码以简化。
这一直有效到现在。
mail -a file.txt -s "Test" [email protected] < /dev/null
身体（！）结果是：没有附加！
file.txt
MIME-Version: 1.0
Content-Type: text/plain; charset="ANSI_X3.4-1968"
Content-Transfer-Encoding: 8bit
文件本身没有附加！显然只发送了编码的标头。
下次尝试：
uuencode file.txt file.txt | mail -s "Test" [email protected]
这一次，body (!) 结果是：没有显示附件！
begin 644 file.txt
M0D5'24XZ5D-!3$5.1$%2#0I615)324]..C(N,`T*4%)/1$E$.BTO+V=E;VAE
M:2!S;V9T=V%R92\O3D].4T=-3"!R;W-T;VEC<R\O14X-"DU%5$A/1#I054),
...
这一次，文件显然被编码，但显示为正文，而不是附件。
我在 2 个不同的客户端和一个 webmail 界面上检查了邮箱。所有相同，从不附加。
mutt（而不是mail）也没有生成文件附件。所以我猜这个问题是系统相关的，而不是mail相关mutt的。
这里出了什么问题？
我刚刚从我的服务器提供商那里收到邮件，说我的服务器正在发送邮件。我不知道这些邮件，而且我之前从未使用过该服务器的 smtp 。谁能指导我如何做到这一点？谢谢

# TRUST AND RELAY CONTROL
# The mynetworks parameter specifies the list of "trusted" SMTP
# clients that have more privileges than "strangers".
#
# In particular, "trusted" SMTP clients are allowed to relay mail
# through Postfix. See the smtpd_recipient_restrictions parameter
# in postconf(5).
#
# You can specify the list of "trusted" network addresses by hand
# or you can let Postfix do it for you (which is the default).
#
# By default (mynetworks_style = subnet), Postfix "trusts" SMTP
# clients in the same IP subnetworks as the local machine.
# On Linux, this does works correctly only with interfaces specified
# with the "ifconfig" command.
#
# Specify "mynetworks_style = class" when Postfix should "trust" SMTP
# clients in the same IP class A/B/C networks as the local machine.
# Don't do this with a dialup site - it would cause Postfix to "trust"
# your entire provider's network. Instead, specify an explicit
# mynetworks list by hand, as described below.
#
# Specify "mynetworks_style = host" when Postfix should "trust"
# only the local machine.
#
#mynetworks_style = class
#mynetworks_style = subnet
#mynetworks_style = host
# Alternatively, you can specify the mynetworks list by hand, in
# which case Postfix ignores the mynetworks_style setting.
#
# Specify an explicit list of network/netmask patterns, where the
# mask specifies the number of bits in the network part of a host
# address.
#
# You can also specify the absolute pathname of a pattern file instead
# of listing the patterns here. Specify type:table for table-based lookups

# The relay_domains parameter restricts what destinations this system will
# relay mail to. See the smtpd_recipient_restrictions description in
# postconf(5) for detailed information.
#
# By default, Postfix relays mail
# - from "trusted" clients (IP address matches $mynetworks) to any destination,
# - from "untrusted" clients to destinations that match $relay_domains or
# subdomains thereof, except addresses with sender-specified routing.
# The default relay_domains value is $mydestination.
#
# In addition to the above, the Postfix SMTP server by default accepts mail
# that Postfix is final destination for:
# - destinations that match $inet_interfaces or $proxy_interfaces,
# - destinations that match $mydestination
# - destinations that match $virtual_alias_domains,
# - destinations that match $virtual_mailbox_domains.
# These destinations do not need to be listed in $relay_domains.
#
# Specify a list of hosts or domains, /file/name patterns or type:name
# lookup tables, separated by commas and/or whitespace. Continue
# long lines by starting the next line with whitespace. A file name
# is replaced by its contents; a type:name table is matched when a
# (parent) domain appears as lookup key.
#
#
#relay_domains = $mydestination
# INTERNET OR INTRANET
# The relayhost parameter specifies the default host to send mail to
# when no entry is matched in the optional transport(5) table. When
# no relayhost is given, mail is routed directly to the destination.
#
# On an intranet, specify the organizational domain name. If your
# internal DNS uses no MX records, specify the name of the intranet
# gateway host instead.
#
# In the case of SMTP, specify a domain, host, host:port, [host]:port,
# [address] or [address]:port; the form [host] turns off MX lookups.

# INPUT RATE CONTROL
#
# The in_flow_delay configuration parameter implements mail input
# flow control. This feature is turned on by default, although it
# still needs further development (it's disabled on SCO UNIX due
# to an SCO bug).
#
# A Postfix process will pause for $in_flow_delay seconds before
# accepting a new message, when the message arrival rate exceeds the
# message delivery rate. With the default 100 SMTP server process
# limit, this limits the mail inflow to 100 messages a second more
# than the number of messages delivered per second.

# TRANSPORT MAP
#
# See the discussion in the ADDRESS_REWRITING_README document.
# ALIAS DATABASE
#
# The alias_maps parameter specifies the list of alias databases used
# by the local delivery agent. The default list is system dependent.
#
# On systems with NIS, the default is to search the local alias
# database, then the NIS alias database. See aliases(5) for syntax
# details.
#
# If you change the alias database, run "postalias /etc/aliases" (or
# wherever your system stores the mail alias file), or simply run
# "newaliases" to build the necessary DBM or DB file.
#
# It will take a minute or so before changes become visible. Use
# "postfix reload" to eliminate the delay.
#
#alias_maps = dbm:/etc/aliases
alias_maps = hash:/etc/aliases
#alias_maps = hash:/etc/aliases, nis:mail.aliases

# The alias_database parameter specifies the alias database(s) that
# are built with "newaliases" or "sendmail -bi". This is a separate
# configuration parameter, because alias_maps (see above) may specify
# tables that are not necessarily all under control by Postfix.

alias_database = hash:/etc/aliases
#alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases
# ADDRESS EXTENSIONS (e.g., user+foo)
#
# The recipient_delimiter parameter specifies the separator between
# user names and address extensions (user+foo). See canonical(5),
# local(8), relocated(5) and virtual(5) for the effects this has on
# aliases, canonical, virtual, relocated and .forward file lookups.
# Basically, the software tries user+foo and .forward+foo before
# trying user and .forward.
#
#recipient_delimiter = +
# DELIVERY TO MAILBOX
#
# The home_mailbox parameter specifies the optional pathname of a
# mailbox file relative to a user's home directory. The default
# mailbox file is /var/spool/mail/user or /var/mail/user. Specify
# "Maildir/" for qmail-style delivery (the / is required).
#
#home_mailbox = Mailbox
#home_mailbox = Maildir/
# The mail_spool_directory parameter specifies the directory where
# UNIX-style mailboxes are kept. The default setting depends on the
# system type.
#
#mail_spool_directory = /var/mail
#mail_spool_directory = /var/spool/mail
# The mailbox_command parameter specifies the optional external
# command to use instead of mailbox delivery. The command is run as
# the recipient with proper HOME, SHELL and LOGNAME environment settings.
# Exception: delivery for root is done as $default_user.
#
# Other environment variables of interest: USER (recipient username),
# EXTENSION (address extension), DOMAIN (domain part of address),
# and LOCAL (the address localpart).
#
# Unlike other Postfix configuration parameters, the mailbox_command
# parameter is not subjected to $parameter substitutions. This is to
# make it easier to specify shell syntax (see example below).
#
# Avoid shell meta characters because they will force Postfix to run
# an expensive shell process. Procmail alone is expensive enough.
#
# IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN
# ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER.
#
#mailbox_command = /some/where/procmail
#mailbox_command = /some/where/procmail -a "$EXTENSION"
# The mailbox_transport specifies the optional transport in master.cf

#
#
# To use the old cyrus deliver program you have to set:
#mailbox_transport = cyrus
# The fallback_transport specifies the optional transport in master.cf
# to use for recipients that are not found in the UNIX passwd database.
# This parameter has precedence over the luser_relay parameter.
#
# Specify a string of the form transport:nexthop, where transport is
# the name of a mail delivery transport defined in master.cf. The
# :nexthop part is optional. For more details see the sample transport
# configuration file.
#
# NOTE: if you use this feature for accounts not in the UNIX password
# file, then you must update the "local_recipient_maps" setting in
# the main.cf file, otherwise the SMTP server will reject mail for
# non-UNIX accounts with "User unknown in local recipient table".
#
#fallback_transport = lmtp:unix:/var/lib/imap/socket/lmtp
#fallback_transport =
# The luser_relay parameter specifies an optional destination address
# for unknown recipients. By default, mail for unknown@$mydestination,
# unknown@[$inet_interfaces] or unknown@[$proxy_interfaces] is returned
# as undeliverable.
#
# The following expansions are done on luser_relay: $user (recipient
# username), $shell (recipient shell), $home (recipient home directory),
# $recipient (full recipient address), $extension (recipient address
# extension), $domain (recipient domain), $local (entire recipient
# localpart), $recipient_delimiter. Specify ${name?value} or
# ${name:value} to expand value only when $name does (does not) exist.
#
# luser_relay works only for the default Postfix local delivery agent.
#
# NOTE: if you use this feature for accounts not in the UNIX password

# JUNK MAIL CONTROLS
#
# The controls listed here are only a very small subset. The file
# SMTPD_ACCESS_README provides an overview.
# The header_checks parameter specifies an optional table with patterns
# that each logical message header is matched against, including
# headers that span multiple physical lines.
#
# By default, these patterns also apply to MIME headers and to the
# headers of attached messages. With older Postfix versions, MIME and
# attached message headers were treated as body text.
#
# For details, see "man header_checks".
#
#header_checks = regexp:/etc/postfix/header_checks
# FAST ETRN SERVICE
#
# Postfix maintains per-destination logfiles with information about
# deferred mail, so that mail can be flushed quickly with the SMTP
# "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld".
# See the ETRN_README document for a detailed description.
#
# The fast_flush_domains parameter controls what destinations are
# eligible for this service. By default, they are all domains that
# this server is willing to relay mail to.
#
#fast_flush_domains = $relay_domains
# SHOW SOFTWARE VERSION OR NOT
#
# The smtpd_banner parameter specifies the text that follows the 220
# code in the SMTP server's greeting banner. Some people like to see
# the mail version advertised. By default, Postfix shows no version.
#
# You MUST specify $myhostname at the start of the text. That is an
# RFC requirement. Postfix itself does not care.
#
#smtpd_banner = $myhostname ESMTP $mail_name
#smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)
# PARALLEL DELIVERY TO THE SAME DESTINATION
#
# How many parallel deliveries to the same user or domain? With local
# delivery, it does not make sense to do massively parallel delivery
# to the same user, because mailbox updates must happen sequentially,
# and expensive pipelines in .forward files can cause disasters when
# too many are run at the same time. With SMTP deliveries, 10
# simultaneous connections to the same domain could be sufficient to
# raise eyebrows.
#
# Each message delivery transport has its XXX_destination_concurrency_limit
# parameter. The default is $default_destination_concurrency_limit for
# most delivery transports. For the local delivery agent the default is 2.
#local_destination_concurrency_limit = 2
#default_destination_concurrency_limit = 20
# DEBUGGING CONTROL
#
# The debug_peer_level parameter specifies the increment in verbose
# logging level when an SMTP client or server host name or address
# matches a pattern in the debug_peer_list parameter.
#
debug_peer_level = 2
# The debug_peer_list parameter specifies an optional list of domain
# or network patterns, /file/name patterns or type:name tables. When

# increase the verbose logging level by the amount specified in the
# debug_peer_level parameter.

#
# Use "command .. & sleep 5" so that the debugger can attach before
# the process marches on. If you use an X-based debugger, be sure to

您好，我已经在网上查看了许多不同的指南，以了解如何从 ubuntu 18.04 将系统邮件发送到我的 gmail，以防设备/服务器出现问题 - 但找不到我认为有意义的简单指南？有人有什么建议吗？
我不想设置邮件服务器，但当我是初学者时，请尽量保持简单。如果我可以使用 google smtp 服务器来做到这一点，那将是一个优势，而不必弄乱我自己的域:)
警报现已关闭，因此想正确解决此问题：
delivery temporarily suspended: Host or domain name not found. Name service error for name=gmail.com type=MX: Host not found, try again
当我试图弄清楚如何让下面的工作正常工作时，我有预感我的问题开始了（即你不直接编辑 resolv.conf ）
cat /etc/resolv.conf
nameserver 192.168.1.1
resolv.conf -> /run/systemd/resolve/resolv.conf
我需要设置一个邮件服务器。我有几个不同的域，我需要为彼此设置不同的电子邮件。
例如：
domain1.com -> [email protected]
domain2.com -> [email protected]
有什么建议吗？
