Thanks very much for the link (printing the page now). This looks very much
like the steps I took on Exchange 5.0 but could not recall how to do.

Two issues with email - one led me to the other....

1. User is having .zip files stripped off of inbound email from a customer.
Although Symantec AV on the server filters most attachments I must allow
.zip files due to customer volume. Even with .exe and others they get
quarantined not deleted. I KNOW for certain .zip files are allowed yet one
user receives only an attached .txt file with a message that the attached
file was deleted by the "antivirus service". All of our Symantec AV
notifications spell out "Symantec AV" as the source. I suspect the problem
is at the sending end want to rule out the user's Outlook 2000 before I
accuse a customer. As far as I know Outlook2K does not have the ability to
strip out attachments. Right?

2. While investigating #1 I see on our Exchange 5.5 server that there is a
large number of SMTP queues with strange names that look suspiciously like
spam sources. While investigating further I see that Internet Relay seems
to be set up - if I am reading the Help screens correctly. Anonomous access
is check marked so in theory anyone can send thru our server. I unchecked
anonomous and all the sudden external email stopped coming in. Any hints
how to be sure we are not an inadvertant relay? Are those SMTP queues
normal? While I was digging around I set the limit on recipients in
outbound messages from 64,000 down to 100 - since we are not a spammer no
harm in that right?

Thanks,

Todd,

I'll 2nd Jim's weblink on 5.5 - did exactly that on mine to stop relaying.

On the 1st issue - suggest that then sender rename his attachments to
*.zipsave before sending. You can rename them back to *.zip on receipt.
