i have been receiving a significant amount of spam that is address to firstname.lastname@example.org
and it also has a sender address of email@example.com
. Normally SA and/or hMail's spam protection catches it and it is dumped into my spam folder. But i got curious as to why so much was getting past the gray list. I picked a few messages and went to look up their IP in the gray list table and to my surprise there wasn't an entry for them. Upon further inspection I discover that there was no entries where glsenderaddress was set to mydomain.com.
So is this behaivor expected or is it a bug? It seems like a bug to me...at least i can't think of a reason that it should do this.
