Hi I have little problem with debian10 and dovecot 2.2.33.2

ps -ax 21815 ? S 0:00 dovecot/pop3-login director 21816 ? S 0:00 dovecot/pop3-login director 21817 ? S 0:00 dovecot/pop3-login director 21818 ? S 0:00 dovecot/pop3-login director 21819 ? S 0:00 dovecot/pop3-login director 21821 ? S 0:00 dovecot/pop3-login director 21822 ? S 0:00 dovecot/pop3-login director

But if I testes via telnet like this:

telnet 46.xxx.xxx.113 143 Trying 46.xxx.xxx.113... Connected to 46.xxx.xxx.113. Escape character is '^]'.
