儘管配置說埠 587,Postfix 仍然使用埠 25
我有一個後綴伺服器,它是主郵件伺服器的中繼。
當我在其上執行 telnet 時,該主郵件伺服器將與 587 埠一起使用,它工作得很好:
telnet 10.10.10.10 587 Trying 10.10.10.10... Connected to 10.10.10.10 Escape character is '^]'. 220 front1 SMTP Server (Flowmailer SMTP Service) ready
這是我在我的聲明中的方式
/etc/postfix/main.cf
:relayhost = [10.10.10.10]:587
這就是我在我的聲明中的方式
/etc/postfix/master.cf
:submission inet n - n - - smtpd
之後我重新啟動了我的後綴
systemctl restart postfix
並且到目前為止沒有收到任何錯誤消息。
然後我嘗試通過我的中繼發送電子郵件,這是我遇到的錯誤:
2022-03-03T11:27:31.031822+01:00 mypostfix postfix/error[32000]: 044D63FBFA: to=<recipient@company.com>, relay=none, delay=0.01, delays=0.01/0/0/0.01, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to 10.10.10.10[10.10.10.10]:25: Connection timed out)
而且我不明白為什麼當我說我想使用埠 587 時它一直嘗試使用埠 25。我在這裡缺少配置文件嗎?

我的域也是
mylocaldomain.com
,我正在嘗試向自己發送一封電子郵件,為此recipient@company.com
我使用包含transport
此行的文件:company.com smtp:10.10.10.10
在您的傳輸文件中,您聲明域
company.com
後綴應使用smtp
傳輸(即埠 25)。所以我猜你的後綴會為所有其他域使用埠 587,除了
company.com
.
