I'm running into some issues setting up hMailServer to use the local SMTP on my server. I've got the local SMTP running and can send mail using telnet and through local .NET apps.
The issue is with getting it to work with forwarding incoming email. I've got a few accounts set up under hMailServer and can get access to POP3 email accounts no problem. It's just getting it all to hang together that I'm having issues with.
If disable the local SMTP and enable it on hMailServer with a relay (I used Gmail) everything works okay apart from the forwarded emails showing up as "via email@example.com".
If I enable the local SMTP and disable it on hMailServer (keeping POP3 running) then I don't get any emails through hMailServer - when I leave logging on, nothing is coming through.
I can't run both the local SMTP and the hMailServer SMTP at the same time (Windows one refuses to start).
If I don't enter anything for the relay address in hMailServer's SMTP settings, the diagnostics show it trying to connect to mail.hmailserver.com. The hMailServer instructions state serveral times not to use localhost as the relayer so I've not tried that.
On my firewall, I've got port 25 open for outgoing and 25 and 110 open for incoming.
What I'd like is for hMailServer to handle incoming email and use the local SMTP to send out.
Is there something simple that I'm missing on doing? Any suggestions would be very welcome.
