Hi all, nothing has changed, or perhaps I have just noticed this problem.
I will notice the queue building up to about 20 - 50 messages, and then they will dump into the undeliverable messages group. After about 3 - 5 minutes they will release from there.
I have a Barracuda smarthost for the outbound mail set in the SMTP routing connector (not the virtual server) and again, nothing has changed. I have the Barracuda set to inbound and it is working as I can send test emails in (they immediately arrive), and again, they eventually leave. I performed the nslookup, set type = mx and did a 'domain.com' lookup and it came back ok. I am just wondering if this is something that I should really worry about or is there some registry setting that a service pack (which have not applied for a month now) may have set...
Also, yes I can telnet to barracuda pt 25 from the exchange server.
Thanks in advance.
