| 3 questions:
1. i get event 2012 in event viewer every now and then:
"SMTP could not connect to the DNS server '192.168.101.101'. The
protocol used was 'UDP'. It may be down or inaccessible."
i didnt configure this dns server anywhere and i want the smtp server
to use normal dns lookups using the local computer (thats the 'normal'
way, right?)
how do i solve this?
2. Badmail incidents: i gets lots of unsent mail, like 10% of my mail.
the adresses & mails are all valid & reachable.
they all look like this:
"Unable to deliver this message because the follow error was
encountered: "This message is a delivery status notification that
cannot be delivered.".
The specific error code was 0xC00402C7.
The message sender was <>."
how do i fix this? 10 minutes later if i re-send the mail manually it
works..
3. how does iis behave in case of unexpected shutdowns? if it was
exactly processing a message, etc. is there anyway that a message can
get "lost"?
thank you.
