Cannot send email larger than 10MB

I am working on a network running exchange 2003 on Small Business Server 2003. Users are unable to send emails larger than 10 MB outside of the orginization. They can send to eachother. This is a copy of the kickback message I get imediately:

This message is larger than the current system limit or the recipient's mailbox is full.  Create a shorter message body or remove attachments and try sending it again.
>             <2K3SERVER.example.net #5.2.3 smtp;450 5.2.3 Msg Size greater than allowed by Remote Host>

I assumed from the last line that is might be the mail server I am sending it to but I tried sending to multiple different recipients including another exchange server which I know can receive mail larger than 10MB. I made sure that I changed it in Global settings/Message Delivery, Default SMTP Virtual server, Small business SMTP connector, & The users Active directory exchange general settings to allow larger attachments (100 MB). Is there anything else I need to change?

Are you routing your email through an ISP using a smart host? If so they could be restricting the size of emails.

I am not sure what is stopping me except for maybe the recipients mail server. Closing question
