Hi Eric Thanks for your reply.
Bare with me, I have partially inherited support for these boxes, so I am not an experienced Imail admin ;-) Both servers only have one dns server listed in the Imail administrator(can only see space for one entry actually, unless you seperate with commas?) and have been rebooted multiple times. We have also tried changing the dns server to an external public server but with no improvement. Just tried it again, for sanitys sake - Still no joy :-( Its almost like its outbound smtp requests are just going to a null adaptor. Is there anyway to debug smtp32.exe any deeper? the "smtp32.exe -v" does nothing when executed from the commandline, and using "smtp32.exe -qr" or "smtp32.exe -v -qr" generates the same log errors.
