这是我的 /etc/hosts 文件
127.0.0.1 localhost.localdomain localhost
127.0.1.1 ubuntu-server.xx.com ubuntu-server
193.77.xx.xx mail.xx.com mail
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
这是我的邮件服务器的正确配置吗？我位于路由器后面，所以我不知道是否可以将我的 IP 用于 mail.xx.com 并将 127.0.0.1 用于本地主机
问题是我可以接收邮件，但是当我发送邮件时，我收到了
Oct 17 21:29:32 ubuntu-server postfix/smtpd[2453]: warning: SASL authentication failure: Password verification failed
Oct 17 21:29:32 ubuntu-server postfix/smtpd[2453]: warning: my.router[192.168.1.1]: SASL PLAIN authentication failed: authentication failure

编辑：
可能是某些端口有问题。我转发了这些端口。
POP3 - port 110
IMAP - port 143
SMTP - port 25
HTTP - port 80
Secure SMTP (SSMTP) - port 465
Secure IMAP (IMAP4-SSL) - port 585
StartTLS - port 587
IMAP4 over SSL (IMAPS) - port 993
Secure POP3 (SSL-POP) - port 995

Cannot find the smtp_sasl_password_maps parameter in main.cf.
Client-side SMTP AUTH cannot work without this parameter!
答案1
输出saslfinger是不言自明的：
Cannot find the smtp_sasl_password_maps parameter in main.cf.
Client-side SMTP AUTH cannot work without this parameter!
创建一个文件（例如/etc/postfix/sasl_passwd，确保只有 root 有权访问该文件！）并输入中继主机的主机名以及您的凭据：
mailrelay.example.com username:password
用于postmap从文本文件创建地图：
postmap hash:/etc/postfix/sasl_passwd
然后指向$smpt_sasl_password_maps它（在main.cf）：
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
重新加载 Postfix。
