每个邮件服务器上的后缀超时

我只是在服务器上没有足够的 inode 后遇到了问题，我修复了这个 postfix 问题。我使用
dovecot+amavis+spamassasin+dovecot+postfix

我发现了这个错误

postfix/smtpd[1775]：警告：主机名 foo.domain.tld 无法解析为地址

电子邮件现在卡在 mailq 中，看起来像这样：

（交付暂时暂停：连接到 alt2.gmail-smtp-in.l.google.com[142.250.4.26]:25：连接超时）[email protected]

我已经尝试过：

import_environment = MAIL_CONFIG MAIL_DEBUG MAIL_LOGTAG TZ XAUTHORITY DISPLAY LANG=C RESOLV_MULTI=on

和

smtp_host_lookup = native

可悲的是，这些都不起作用。

这是我的

/etc/hosts

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
