Hi everyone I'm using a self-hosted wordpress blog. I'm using Gmail to access my domain email accounts. I want to know, is built-in email services such as exim, etc are necessary if we are using Gmail to manage emails? I have only 2 accounts on server: root and my personal account. I have set "Mailserver selection" to Disabled in WHM settings. My problem is that I regularly get following alerts from LFD: ========== Time: Sat Jan 5 08:53:07 2013 IP: x.x.x.x Failures: 2 (pop3d) Interval: 300 seconds Blocked: Permanent Block Log entries: Jan 5 08:53:00 host dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<staff>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x Jan 5 08:53:03 host dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<sales>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x ========== I generally get 1 or 2 emails daily. I have set the pop3 login failure attempts to 2 before permanent block in firewall settings. But I want to know, is there any way to permanently stop these attacks? Can I disable exim or any other thing which can stop these attackers? Thanks.
