no firewall. I can connect to the imap server on port 143 just fine. I just can't send emails to the local accounts by using port 25.

Someone mentioned before about hosts.allow and deny

Seeing as I'm denying everything in hosts.deny I had to put in hosts.allow

sendmail:ALL

to allow access.



Just about the only other things I changes in sendmail.cf was this line:

O DaemonPortOptions=Port=smtp,Addr=192.168.1.100,127.0.0.1, Name=MTA

Although I did the bad thing and edited it manually after making a backup of it

Apart from that just the usual entries in the access file for relaying got it working for me.
