    In my sys logs,

    I keep getting this error:
    Sep 21 21:58:25 Server1 dovecot: pop3-login: Aborted login (auth failed, 3 attempts): method=PLAIN, rip=, lip=, TLS

    this problem with this error is that the IP address its complaining about is the server IP, dose this have anything to do with fail2ban?
    note: that when my server was setup i used the ispconfig 3 ubuntu 12.04 guild, also IP= is an example of my server address,
    and pop3 port is already open.

    please advise

    According to the line, someone tries to connect to po3 from your server. maybe a script like a ticket system or shop that tries to fetch emails and uses a wrong password?
