SYMPTOMS
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 -

Last-Attempt-Date: Fri, 2 May 2003 16:59:59 -0400 (EDT)



CAUSE
This issue occurs because of firewall size restrictions for e-mail attachments.



WORKAROUND
To work around this issue, remove the firewall restrictions. When you do this, large e-mail attachments can be delivered.
