Some attachments not getting through, plain text OK.
We are experiencing a strange phenomenon where people who communicate with us regularly are not able to send emails with attachments. regular emails with no attachments before or after they attempt the attachment come through fine, but the mail with the attachment generates a delay message and ultimately an NDR saying the connection timed out or some such thing.
Sometimes the same party can send attachments and they come through ok.
We are running Exchange 2003 standard on a Server 2003 Enterprise machine. The Exchange DB is 14.3G in size.
Thanks for looking.

What connection to the Internet and what is the service pack level of the servers (please include the Exchange Server SP also)
ASKER
Internet Connex is mult-T1.
Server is SP1
Exchange is also SP1
Server is SP1
Exchange is also SP1

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
If your Exchange DB (priv1.edb) is 14Gb then it is possible that with the priv.stm you are getting very close to Exchange SP1's 16GB limit and this may be why the attachments are being rejected. Upgrade to SP2 and you will be allowed to have a 75GB DB.

Ok, thanks for that tip...
The 14 gig includes the edb and stm files. Plus there's almost a gig of whitespace.
Downloading SP2 now.

Anything else on the server?
Exchange itself cannot reject applications - but third party products can.
I have also seen similar problems caused by a firewall with SMTP scanning features. The size of the email causes the scanning feature to drop the connection.

GFI Mail Essentials is the only other thing on the server. It is not configured to refuse attachments.
It isn't the blocking of attachments that I was worried about.
It is the simple time out of the connection stopping the attachment from being delivered correctly. That would explain connection time out issues.
Is this more than one site having the problem? If it is just one domain then it may not be something that you have changed.

Gotcha.
It is occurring with mail from more than one domain.
It is occurring with mail from more than one domain.
If it is more than one domain and there is no common pattern between the domains then I would start looking at the path the email message takes to get to the mailbox.
That includes looking at the firewall and any products that could be scanning the message. Ensure that any antivirus products are not scanning any part of the Exchange directories, or directories that other products might use as a hold zone.

After installing SP2 this morning, I got a mail sent a few days ago w/attachment.
I checked the A/V scanner and ensured the proper directories were excluded from scanning.
