Re: SMTP Server Retry Question

Rob,

Can you ping that address?

Not during the outage this past weekend. Our firewall had a hardware
failure so we were completely cut off from the outside world. At one point
when the new firewall was mostly configured I could ping the external mail
server, but couldn't telnet to port 25. Connectivity to the external mail
server was restored around mid-day Saturday. With such a network issue,
outgoing mail should have been queued up and sent out once connectivity was
restored. But that doesn't appear to have happened.
