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.

1. It should use the DNS server configured under network settings.

2. Sounds like you may be an open relay, what are your relay settings ?
I would assume the failed delivery is because of the DNS issue.

3. You can configure the SMTP Service to restart under the services panel,
however I have never seen it crash that bad, if that happens you probably
have some
other issue on the computer.

1. My Network Settings configuration is set to automatically find the
dns. what should i do to solve the "SMTP could not connect to the DNS
server '192.168.101.101'. The[vbcol=seagreen] 
where did ip '192.168.101.101' come from? i didnt define it anywhere..

2. The purpose of my server is something like mail filtering. user
x@a.com sends a msg to user@myserver.com, and i pass it to y@b.com,
where b.com can be ANY SERVER in the world. is there a way to do this
without open relay? (i understood that open relay might be considered
spamming)

3. i just wanted to know if someone encountered a mail-loss after a
crash, or is iis' smtp safe enough to handle this.

thanks
