IMHO MS is right: We have had similar problems in the past. Every time it
happened, our firewall people claimed innocence, and every time they were
eventually proven guilty.

Betreff: Multiple bounce backs
This is what is happening: A user sends an email to a bad address
and receives this error:,[EMAIL PROTECTED]
Obviously, the syntax is incorrect with that comma in the beginning of it.
The user receives the following message multiple times.
553 ,[EMAIL PROTECTED]... Unbalanced ''
553 [EMAIL PROTECTED]... Unbalanced ''
550 ... User unknown
553 ',[EMAIL PROTECTED]' ,[EMAIL PROTECTED], Hurst,
Fiona
[EMAIL PROTECTED]... Unbalanced ''
553 [EMAIL PROTECTED], Hurst, Fiona
[EMAIL PROTECTED]... Unbalanced ''
In addition, if there were any other CC'd users in this, they will receive
the message multiple times as well.
What I have done in the past, is to manually remove the message from the
outbound queue which stops the problem.
Our current configuration is Exchange 5.5 sp4 with post sp4 hotfixes,
Antigen version 6.20.0842
A Gauntlet Firewall (which I don't administer so I don't have much info
about it)
Our IMC uses straight IP to point to the firewall, instead of using DNS.
We have tried the DNS setting, and this fixed the situation, however, due
to internal DNS situations, we can't keep this configuration.
I've spoken to Microsoft a multitude of times about this and they keep
blaming the firewall. Of course, the firewall people keep blaming
Exchange.
Has any one seen this, or have any suggestions?
Thanks
