在 Ubuntu 18.04 服务器 (VM) 上，我有一个配置了 LDAP 登录的 gitlab omnibus 安装 (12.10.6)。除了 LDAP，我没有更改配置默认值。
目前，gitlab 还无法发送电子邮件，例如提及问题等。以下是摘录/var/log/mail.log（我更改了真实的域和用户名，但除此之外，它是实际的日志）：

尝试向[email protected]联系人发送电子邮件时postrelay1.lrz.de，邮件被退回550 Requested action not taken: mailbox unavailable (in reply to RCPT TO command)。我多次检查用户名是否正确，邮件是否可以投递给 gitlab 服务器之外的收件人。此外，其他域（例如 ）也发生了同样的事情，[email protected]所以smtpin.rzone.de我认为问题出在其他地方。
我读过有时 550 也可能意味着服务器将电子邮件视为垃圾邮件...但我对邮件服务器不是很熟悉。
这是后缀main.cf：
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
compatibility_level = 2
inet_interfaces = all
inet_protocols = ipv4
mailbox_size_limit = 0
mydestination = $myhostname, mydomain.intern, gitlab, localhost.localdomain, localhost
myhostname = mydomain.intern
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost =
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
任何指示或想法表示赞赏

该消息550 Requested action not taken: mailbox unavailable表明收件人邮件服务器存在问题。大多数情况下，这意味着电子邮件地址无效。您唯一能做的就是确保您正确拼写了电子邮件地址。如果这不能解决问题，预期收件人将需要联系他们自己的电子邮件提供商寻求帮助。这不是你能解决的问题。
