server wide email blocking
OK, I'm stumped.
I'm trying to get account information emailed to me from vbulletin and no matter what email address on my server I used it never arrives. This is a recent problem because i have not had problems receiving email from them in the past.
I don't have any email filtering in place on the server and I even went and deleted all the email accounts on the hmtk.com domain and rebuilt them again. I'm still getting all the spam I got before but I am no closer to figuring out why this one domain would be blocked. My next step is to contact the company that hosts my server but I can't think of any reason why they would be blocking email from vbulletin.com.
Any suggestions of where to look?
Right now I'm going through my /usr/local/psa/var/log/maillog file with vi doing /variable. to look for instances of their emails coming in and bouncing but no luck yet.
