I get a sinking feeling when this happens. This has happened three times and every time the domains have been blacklisted and it has always been a hacked password and someone externally is using the hacked account to send email.

If I use mxtoolkit

https://mxtoolbox.com

under "more information" it says
The SpamCop Blocking List lists IP Addresses which have sent unsolicited email to SpamCop users. This is often an indication of a Virus or Botnet from a Malware infection contracted inside your network.

So , i am wondering what might be happening

Might I have a bot somewhere
such as
an account has been compromised ? a bad guy has the login & psswd and is now spamming?

how could/can i tell?
a look at the logs?
where ? how?

would i monitor port 25 on my network?

any wisdom is welcomed.

to be clear. I am not a spammer - just a small bussiness with a qmailtoster and ... now I have this matter


any wisdom is welcomed.

thanks in advance
