it seems that my mail server does appear on a blacklist .
spamcop
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
