    Why directadmin don't see port 110

    Hello guys

    When I tryied run emails on my server (pop,smtp), i found error.

    debian:/etc/dovecot# telnet localhost 110
    telnet: Unable to connect to remote host: Connection refused
    debian:/etc/dovecot# nmap localhost

    The POP3 protocol requires that port 110 be open and listening. According to your nmap output, either you've got port 110 blocked by your firewall (unlikely since the test is by localhost) or Dovecot isn't running.
