Annoying Email Login attempts using Google IP Addresses

[madamsplash]

Every day my dedicated server is attacked by somebody who attempts to login to an email account that has not been used for sometime on two of our web accounts using a variety of Google Addresses ... anywhere up to 5000 times a day

The result is to block Google from spidering our servers and sites ... the offender obviously knows a little bit about the way our email works and is running a private server.

Is it possible to stop a single email account login attempts and still set allow the IP Addresses in IP Allow? (See messages below)

-----------------------------

I'm also getting daily notification of suspicious process running under user (then proceeds through all websites on the server - only a few at the moment) /usr/sbin/pure-ftpd\00i686\00hp .......... (deleted)

"This file system shows this process is running an executable file that has been deleted. This typically happens ..... See csf.conf and the PT_DELETED text for more information .... etc"

Anything I should be concerned about with message like these?

Hey there,

Is it possible that - and I'm just speculating - this user has their webmail client open on GMail and the IMAP/POP is trying to get mail from your server, but their username/password is wrong? Just thinking out loud since really it seems to be the same user @ multiple domains that's failing... the user on Google's end may not even realize their password is incorrect.

If not, then you may have a really awesome hacker on your hands with lots of rooted boxes in Google's server fleet... which I doubt.

If you think the idea of Webmail fetching mail and failing isn't quite right, I would suggest you e-mail [email protected] or something to that effect.

Their whois data: http://who.is/whois-ip/ip-address/74.125.46.141/

A company of that size probably has staff dedicated to this kind of thing.

Warmest regards,

Lol - Probably an awesome hacker ...

We had an employee named Zoe - she lasted one day - one of our former designers had/has a girlfriend named Zoe and I was approached by a Zoe to become a Web Designer.

This person is probably a local dinasoar (bit like moire) from the days when we could all download the software to turn our pc's into internet servers and give it whatever IP address we liked ... Looks like I am alone in the Universe with this cretin :p

Had hoped I could nullify login attempts to the email addresses without blocking from the server entirely ...

Have advised Google - thanks for looking, and if you have any ideas - please advise.
