View Full Version : How to find spam traps

This filter helps find accounts that receive e-mails which don't exist, then you can paste results in Excel, sort and create spam traps for these (in the Limits tab of an account, State -> Spam trap, it will block IP that sent mail for the duration specified in Intrusion Prevention).

All that I miss is some stats in icewarp referent to spam traps.

Where Recipient is local (then choose account does not exist)
and ! Where Sender's IP address is trusted
and ! Where SMTP AUTH
and Where Recipient matches domain1.com;domain2.com
Stop processing more rules
and Forward to cf-find-traps@mydomain.com (create this account with unlimited disk space to avoid NDR)
and Add %%Current_Recipient%% to a file (specify a text file, ex: domain.com/trap.txt)

Note: in domain1.com;domain2.com replace with domains you want to check for destination emails to inexistant account

You can also simply setup catch all on a domain to find emails sent to accounts which you never announced and consider using them as spam trap. Log analyser can be useful to help with suck task also.
