Hi - fresh install of 7.0rc2. Not receiving mail but can telnet from internet to my server on port 25 so it seems server is listening but rejecting mail. Where to start debugging please. I can't find anything useful in the logs.
Regards
Brian
Is that from the putside (WAN side) or the local network (LAN side)? Were you able to run a mailserver in the past?
Most of the times providers don't want there users to have there own mailservers configured and don't accept communictaion to port 25 on there domain to other servers than their own maillservers. This is done as a security measure to prevent spam servers.
However if you have access to the DNS entries for your domain you can set up the mailserver of your provider as a mailrelay so your won mailserver receives all e-mail via the mailrelay server.
It simply works like this: mail which is for a user at your domain is to be delivered at your domain, but your mailserver is not accessible/vissible for other mail servers. The backup server (mailrelay server of your provider) however is, so mail is delivered there. The mailrelay server of your provider is able to see your server and is able to deliver the e-mail that is for users at your domain.
