Message size error

[Davetoo]

I'm getting the following error when sending a 12MB attachment:

#550 5.2.3 RESOLVER.RST.RecipSizeLimit; message too large for this recipient ##

I've set the limits to 20MB on the server based upon this site:

http://blogs.technet.com/sbs/archiv...nge-message-size-limits-in-exchange-2007.aspx

However, I still get the error. I've confirmed all the settings are at 20MB for maximum size, and have tested multiple 12MB files and confirmed in message tracking that the attachment is 12MB.

I can send it internally just fine, but I can't send it to an Internet address. I've tested sending to my personal GMail account which has a 25MB/email limit.

Ideas?

MIME conversion will bloat files, often by more than 30%. There were some internal threads going around about this issue. Let me see if I can get some public info for you.

I've seen the MIME issue before but in the message tracking it will show the "bloated" size. In this case it's remaining at the 12MB size even in message tracking.

I've also tried various file formats with the same result (PDF and a huge spreadsheet).
