Consider the following scenario. In a Microsoft Exchange Server organization, the Exchange Server server has no size restrictions for e-mail attachments and no quota settings on mailboxes. Additionally, size restrictions are set on the firewall.
In this scenario, you may receive non-delivery reports (NDR) when you send e-mail attachments that are larger than a specific size. For example, you may receive an error message that resembles the following error message:
----- The following addresses had permanent fatal errors -----
----- Transcript of session follows -----
... while talking to mail.domain.com.:
<<< 552 Requested mail action aborted: exceeded storage allocation
554 <firstname.lastname@example.org>... Service unavailable
Final-Recipient: RFC822; email@example.com
Remote-MTA: DNS; mail.domain.com
Diagnostic-Code: SMTP; 552 Requested mail action aborted: exceeded storage allocation

This issue occurs because of firewall size restrictions for e-mail attachments.
To work around this issue, remove the firewall restrictions. When you do this, large e-mail attachments can be delivered.
