HI,

Without changeing something I've started to get the following error:

Oct 20 22:17:56 vangelis courieresmtp: id=00000963.4176B9D9.00002800,from=<XX.@dmj.nu>,addr=<XX.@hotmail.com>: DNS lookup failed. Oct 20 22:17:56 vangelis courieresmtp: id=00000963.4176B9D9.00002800,from=<XX.@dmj.nu>,addr=<XX.@hotmail.com>, status: deferred

My qustion Is now, Is this an error in my configuration (I can do a nslookup/host/dig on hotmail.com, and it returns fine) or is this an Error message from my upstream smtp gateway (my esmtproutes only contains ": mail.bluewin.ch")

Found the problem, my upstream provider has changed their DNS so mail.bluewin.ch does not have any MX record anymore. I change my esmtproutes to ":bluewin.ch" and everything works again.

Thanks for the help and for a GOOD piece software! --Dan
