Ubuntu
Dovecot 沒有監聽 imap 和 pop3 埠
在我繼續之前,我在網上查看了大量關於協議未設置的文章,並嘗試了他們提供的內容,但所有這些都無濟於事,似乎也無法解決問題。
我在設置 dovecot 時遇到了一些問題。我一直在遵循本指南:http ://www.krizna.com/ubuntu/setup-mail-server-ubuntu-14-04/來設置郵件伺服器,一切正常。Postfix 已正確安裝和配置。在我進行 Dovecot 安裝時,它詢問我有關使用 telnet 連接並驗證連接是否正常工作(在指南中)以及埠:110,995,993,143是否工作。但是只有埠995和993允許我連接,但它們沒有顯示任何類型的資訊:“+OK Dovecot (Ubuntu) ready。” 在他們。
我在 /var/log/mail.log 中看到了這個:
Jun 26 09:05:07 master: Info: Dovecot v2.2.9 starting up (core dumps disabled) Jun 26 09:05:07 config: Warning: service auth { client_limit=1000 } is lower than required under max. load (6000) Jun 26 09:05:07 config: Warning: service anvil { client_limit=1000 } is lower than required under max. load (6003)
即使我連接到993和995埠。當我嘗試其他的時,我得到:
telnet: Unable to connect to remote host: Connection refused
該過程正在執行,我看不到任何錯誤。這是dovecot -n的輸出

如果您需要更多資訊,請直接說,感謝您的幫助。因為我試圖配置這個東西已經走到了盡頭。
提前致謝。
- 埠 993 和 995 需要 SSL/TLS,您不能簡單地 telnet 到它們並期望以明文形式列印內容。使用類似
openssl s_client -quiet -connect youdomain.tld:993
或openssl s_client -quiet -connect youdomain.tld:995
protocols = imap pop3 imap pop3
<- 為什麼要列出兩次?inet_listener imap { port = 0 }
<- 您在埠 143 上禁用了 IMAP,這就是您無法遠端登錄到該埠的原因。不要禁用 IMAP,disable_plaintext_authentication=yes
如果您想要 TLS 安全登錄,只需使用。inet_listener pop3 { port = 0 }
<- 您在埠 110 上禁用了 POP3,這就是您無法遠端登錄到該埠的原因。不要禁用 POP3,disable_plaintext_authentication=yes
如果您想要 TLS 安全登錄,只需使用。順便說一句,您啟用了 imap 和 pop3 協議並為 lmtp 進行了一些配置,但您沒有啟用 lmtp 協議。
