What - you want to add the \r\r.\r\r in the filter definitions?
Is this sequence sent with or without actual mail content?

Hi,
Is there any way to modify the ISA SMTP filter behaviour outside of the GUI?
We have a customer who is getting a weird error from the SMTP filter when the
*data* portion contains "CR CR . CR CR". The problem is that instead of
rejecting the connection, as I would have expected, the filter returns a 421
error, which essentially means "syntax error (invalid data termination), try
again later" causing a backlog on the upstream SMTP server.
I am guessing this is a log with PSS job to determine if the behaviour is a
bug, or by design...just wondered in anyone had any similar experiences or
thoughts?
Cheers
JJ
