pop3-login: Disconnected - blocked IP ???

[kalil]

Guys,

I have a serious problem.


A domain of a client stopped authenticating POP3, when I switch provider (public IP) accessed normally for a day and went back to being 'locked'.

Is there any tool that blocks IP for pop3?

Webmail works normally, just pop3 blocked


Logs.

pop3-login: Disconnected (auth failed, 1 attempts).



thanks for help.

Hello

Check to see if the IP address is locked out by cPhulkd:

"WHM Home » Security Center » cPHulk Brute Force Protection"

Thank you.
