Hi all,
One of my users sent email someone and received a rejected notice. Here it is:
host mx01.lastspam.com[64.15.150.3] said: 550-5.7.1 rejected content,
black listed 2010.In by multi.surbl.org. #762 #895 (m6F1MY037314479000)
The attachments being sent were a 38 KB Excel file, and 1 MB PowerPoint.
I understand that SURBL checks for websites and URLs inside the email, but I can't seem to find anything about SURBL lists rejecting content. I'm inquiring as we need to make sure these attachments get to the recipient.
Thanks,
Will
