我目前有一个筛滤器，如下所示：
require ["variables", "envelope", "fileinto", "vnd.dovecot.filter", "subaddress"];
if envelope :matches "to" "*" {
set :lower "my_recipient" "${1}";
filter ".." "${my_recipient}";
fileinto "INBOX";
}
这很好用。但是我的过滤器当前无法正确处理子地址，例如：[email protected]
所以我想将my_recipient变量设置为 [email protected] 以使过滤器正常工作，即使信封设置为 [email protected]
我已经阅读了子地址文档，我可以看到如何获取user部分或domain部分，但不知道如何获取完整地址，包括没有detail部分的域。我怎么能做到这一点？
目前我将我的 exim 配置设置为使用外部 SMTP 服务器发送所有电子邮件。所有用户使用本地密码向我的 exim 服务器进行身份验证，然后发送的消息通过智能主机中继到远程 SMTP 服务器，与连接到我的 exim 服务器（运行 cPanel）的用户直接使用的登录相比，该服务器使用不同的登录名. 这是当前的配置：
remote_route:
driver = manualroute
domains = !+local_domains
transport = remote_transport
route_list = * remotesmtpserver.com
remote_transport:
driver = smtp
port = 587
hosts_require_auth = <; $host_address
hosts_require_tls = <; $host_address
remote_login:
driver = plaintext
public_name = LOGIN
hide client_send = : remote_username : remote_password
这一切都运作良好且符合预期。
问题是我想为一组选定的用户/发件人使用不同的 remote_username 和 remote_password。登录名（对于我的 exim 服务器）是完整的电子邮件地址，因此我已将这些电子邮件地址添加到文件 /etc/differentlogin（即，由新行分隔的电子邮件地址列表）。
然后我在 remote_login 部分尝试了以下设置：
remote_login:
driver = plaintext
public_name = LOGIN
hide client_send = ${lookup{$authenticated_id}lsearch{/etc/differentlogin}{: different_username : different_passsword}{: remote_username : remote_password}
但是，这在尝试发送电子邮件时给了我以下 EXIM 错误：
== [email protected] R=remote_route T=remote_transport defer (-48): expansion of "${lookup{$authenticated_id}lsearch{/etc/differentlogin}{" failed in mandrill_login authenticator: missing } at end of string
我尝试使用 $sender_address 而不是 $authenticated_id，但这给了我相同的结果。
我还尝试用字符串替换要搜索的变量，即：
remote_login:
driver = plaintext
public_name = LOGIN
hide client_send = ${lookup{[email protected]}lsearch{/etc/differentlogin}{: different_username : different_passsword}{: remote_username : remote_password}
但我仍然得到同样的错误。
为了检查我的条件语法，我尝试将以下内容添加到我的 remote_transport：
headers_add = X-SenderTest: ${lookup{$authenticated_id}lsearch{/etc/differentlogin}{different}{normal}}
这可以按预期工作，并在从 /etc/differentlogin 列表中记录的地址/登录名发送电子邮件时添加以下标题
X-SenderTest: different
有小费吗？
非常感谢
我在 Exim 中有一个传输设置，我为某些用户添加了一个特殊的标头 - 并为其余用户添加了不同的标头值。我已尝试创建正确的语法来添加此标头，但遇到了一些问题。
我目前的代码是：
headers_add = X-SenderTest: {${lookup{$sender_address}lsearch{/etc/addresses}{header1}{header2}}}
因此，如果 $sender_address 在文件 /etc/addresses 中（只是新行电子邮件地址的列表），我想要以下标题：
X-SenderTest: header1
对于我想要的所有其他 $sender_address ：
X-SenderTest: header2
但是我实际得到的是：
X-SenderTest: {header1} or
X-SenderTest: {header2}
我尝试了多种删除 { 括号的组合，但没有任何运气得到各种语法错误。
例如以下：
X-SenderTest: {${lookup{$sender_address}lsearch{/etc/probanalogin}Prob no-Prob}}
给出这个语法错误：
failed to expand headers_add or headers_remove: missing or misplaced { or }
任何帮助将不胜感激。
我正在运行带有 Software Raid 1 的服务器，它仅用于使用 Idera/R1Soft 进行备份。最近几天，备份生成非常缓慢，所以我开始怀疑是否存在磁盘问题。但是我不确定是否是这种情况，所以希望有人可以帮助我诊断这个问题。
以下是磁盘的大量信息，如果需要其他信息，请告诉我。这些驱动器看起来是否健康，或者似乎是什么问题？备份软件保存到 /home/ 分区，所以这可能是问题所在。
如果其中一个磁盘出现故障，我需要向服务器提供商发送证明，我应该发送什么？
非常感谢！
