我正在尝试让 fetchmail 从 POP3 服务器吸取消息，并将它们插入 Cyrus 以进行本地 IMAP 传送。
Cyrus 本身运行良好，而且我可以使用远程计算机上的 ThunderBird 连接到它。
Fetchmail 似乎正在接收消息，但并没有将它们放在 Cyrus 中（或者任何地方）。
/var/log/mail.log显示：
Aug 5 03:58:57 IMAP postfix/lmtp[8537]: 57ECB1A15BC: to=, relay=none,
delay=77830, delays=77829/0.56/0/0, dsn=4.4.1, status=deferred
(connect to IMAP.IMAP[/var/run/cyrus/socket/lmtp]: No such file or directory)
套接字“/var/run/cyrus/socket/lmtp”确实存在于系统中。它归 root:root 所有，但为了排除故障，我已将其 chmode 设置为 777，因此应该不存在任何权限问题。

我还可以尝试什么？

请检查您的 postfix lmtp 是否通过 master.cf 中的配置进行 chrooted
如果你发现像这样的一行
lmtp unix - - - - - lmtp
甚至
lmtp unix - - y - - lmtp
您需要检查套接字是否存在于 chroot 中（最有可能是 /var/spool/postfix）。
例如：/var/spool/postfix/var/run/cyrus/socket/lmtp 是否存在？（而不是 /var/run/cyrus/socket/lmtp）
如果是这种情况，您可以通过 master.cf 中的以下行从 lmtp 中删除 chrooting：
lmtp unix - - n - - lmtp
或者您可以 mount-bind /var/run/cyrus/socket 以与 chroot 共存。

现在似乎可以正常工作了。我在 postfix/main.cf 中将“myhostname”更改为“localhost”，突然一切似乎都正常工作了。感谢您的回复！
