When I try to send an email to an external domain, I receive this error message:

There was a SMTP communication problem with the recipients email server.  Please contact your system administrator. <ourdomain.local #5.5.0 smtp;500 Firewall Error>

What does this mean? This only occurs when I send emails with attachments.

Check your SMTP settings. You may have to select "My Outgoing Server (SMTP) Requires Authentication.

TK, Are you referring to Outlook 2007 or on Exchange Server 2007?

I don't know of any SMTP settings in Outlook 2007.

Does anyone know if this issue is on my side (Exchange Server or Router) or the destination's (Exchange Server or Router)? I am trying to narrow down where the problem could lie.

qiltjr, your second link is more like what I am experiencing. I also have a Cisco 1760 and use CBAC. The only SMTP inspection occurs from inside to outside. I have disabled this and will try.

Cisco CBAC SMTP inspection generated this error. Apparently ip inspect smtp doesn't work well with Exchange Servers.
