I am having a strange issue where a user cannot receive a 7MB file attachment to our SBS 2008, Exchange 2007 SP2 server. I have searched EE as well as followed the steps outlines here: http://exchangeshare.wordpress.com/2008/04/24/exchange-2007-where-to-set-message-mail-size-limit/
Adjusted the Receive connector from 10MB to 20MB. Restarted the System Attendant and Transport services. Strange part is, the Exchange default is 10MB and the file is only 7MB and we have not had previous issues. No virus scanner or other content filtering in place on the server, but the email does get relayed through MessageLabs for spam and virus checking. However, they don't limit attachments. Below is the bounced message. Thanks in advance.
Could not deliver message to the following recipient(s):
