Outbound e-mail from an internal ms
exchange server to the Internet through
a Fw-1 4.1 SP5 on a Nokia IP-120 using an SMTP resource that passes
the
e-mail to a CVP server (Trend
Interscan virus wall).
When sending e-mails to web based e-mail
services such as hotmail and
yahoo,
we will notice between 3 - 5 "Connection to final MTA failed"
messages in the fw-1 log. When sending them to
private corporate e-mail
accounts,
such as [email protected], we do not get the "Connection to final MTA
failed" messages.
We've already tried settng
Policy-->Properties---> "Accept outgoing
packets originating from gateway" to "first".
However, the symptom still exists.
Can you or someone suggest reasoning as to
why we are getting the
"Connection
to final MTA failed" messages with web based
e-mail destinations and not with private corporate
e-mail destinations?
Can anyone suggest a remedy?
Note, that without using an SMTP resource,
any message to any e-mail
account
passes on the first attempt without any error message.
