I love HelpSpot, but once in a while it gets stuck in an endless e-mail loop.
HelpSpot receives a spam message and it then HelpSpot auto replies to it. HS receives back a “undeliverable address” error message since the spammer forged the return address. Now the loop starts. HS responds to this error message but the return path is to
"<>" and From is “serveradmin@Mailer-Daemon”, so HS responds to “serveradmin@Mailer-Daemon”. Of course my SMTP server rejects the message with an “Unrouteable address”. HS reponds to that messages, and so on, and so on…
Is there a way to prevent HS from enter such a loop with out disabling auto replies? I’ve tried using a Mail Rule to delete the bounced messages, and it does, but HS still auto replies.
