Tagging obvious Spam

Left Menu > Domain Templates > RBL Templates

Add: spamhaus-zen, spamcop.net, sorbs-dnsrbl

Left Menu > Domain Templates > Process Policy

Modify: Spam Lists to Be Spam = 1
(or 2 to be less aggressive)

Modify: Spam Lists to Reach High Score = 2
(or 3 to be less aggressive)

Left Menu > Mailborder Servers > MTA > Edit Postfix

Scroll down to “smtpd_recipient_restrictions” and add this above the “permit” statement:

reject_rbl_client zen.spamhaus.org,
reject_rbl_client bl.spamcop.net,
reject_rbl_client cbl.abuseat.org,
reject_rbl_client b.barracudacentral.org,

This will stop spam from being accepted by the server if the remote MTA is on any of the blacklists.
