我尝试使用 sasl auth 设置我的 postfix smtp。当我在本地服务器上使用 telnet 检查时，它似乎可以正常工作。
输出：
# telnet mail.domain.tld smtp
Trying 37.34.52.199...
Connected to mail.domain.tld.
Escape character is '^]'.
220 mail.domain.tld ESMTP Postfix
ehlo domain.tld
250-mail.domain.tld
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-AUTH PLAIN LOGIN
250-AUTH=PLAIN LOGIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
但是当我尝试测试登录身份验证时，我被困在用户名中：
auth login
334 VXNlcm5hbWU6
dXNlcm5hbWUK
535 5.7.8 Error: authentication failed: VXNlcm5hbWU6
创建的用户名如下：
# echo 'username' | base64
我确信该用户存在，我也使用同一个用户登录了 IMAP。

我建议使用 swaks 来测试 postfix。
swaks -s mail.domain.tld --to [email protected] --from [email protected] --auth LOGIN --auth-user [email protected]
