Has anyone had any luck with this yet?
I have got IIS installed on the server, set the SMTP address in the helpdesks administrator section but the mail ends up in queued then will go to the badmail folder after a few minutes.
I spoke to the council today (who control our internet/firewall) and they say that port 25 is not blocked.
I can't seem to get my head arround the problem.
Can anyone shed a bit of light on the situation?
