I have a Microsoft SBS 2008 server. As of three months ago, I am getting a ton of emails bouncing because of the attachment size. 7mb attachments will get blocked even though the max is set to 10.
Error Message from Destination Mail Server:
552 5.3.4 Message size exceeds fixed maximum message size
These attachments are under our limit. I checked in the three spots in this article: http://www.nogeekleftbehind.com/2011/12/09/show-exchange-message-size-limits-in-sbs-20082011/
and everything was set properly. What else could be stopping this?
