Hello colleagues,
My sme email server has been spam blacklisted.
The network has 250 pc and 330 users (xp, w7, w10, outlook 2007, 2010, 2016 etc).
How do I find a spammer (spammers)?
Is it also possible that the spam is not coming out of the internal network, but through the domain?
I checked the mail log analyzer. Sender Statistic.
Total 12k line ...
my sender statistic log file here:
http://s1.toldacuccot.hu/dl.php?sid=940b04a7c1073a28ddc210d187ca22db&file=senderstatistic.rarrar pwd: koozali.org
What period is this? one day, one week, or all the time?
I don't see a user who has sent thousands of emails to this. How is this possible?
I need to ask for help to get started.
many thanks
