I am having problems with SBS 2008 receiving attachments. The SBS server is set to 15360 KB for send and receive. When I send an email with an attachment of 7 MB to a user I get a message back that says "This message wasn't delivered to anyone because it's too large. The limit is 10 MB. This message is 11 MB." It looks like the emails are increasing in size. I'm not too sure what is causing this.
Thanks for your help.
