Hello Experts,

I have noticed that outgoing email from our exchange server has stopped.

looking at the logs on our juniper for the SMTP outbound permit policy i am seeing

Close - TCP FIN on SMTP traffic from our exchange server.

in the advanced tab we do have the box for source address translation checked.

any ideas?

Create a rule - trust/untrust - ip address of exchange server -> any, service - Mail - permit and log

Restart SMTP service

a  snoop or a flowfilter might help you figure out why the juniper is denying the outbound traffic
