Do you see any attempt to connect in the SmarterMail SMTP logs?  If so what error message is being shone?  If you do not see any connection attempt try to telnet to your mail server using the same settings that SmarterTrack is using and see if you can make a connection.

It's not even showing in the smarter mail log, so it's not even getting that far!

When you telnet what type of response are you receiving?  Also are you using the IP address or hostname?  If it is the hostname try the local IP address since they are on the same box.

Ok after looking through logs the smartertrack SMTP is trying to connect via IPv6 which smarter mail 10.7 doesn't support. I've tried to us an IP, but because it is effectively 'localhost' it defaults to using IPv6. Is there any way to change this? Or allow smartermail to bind an IPv6 my server has?

To change what IP address SmarterMail is listing on login as the system admin and go to Settings | Bindings | IP address then edit the IP address you want SmarterMail to listing on and enable/check the proper protocol.  Also if you do not want SmarterMail to listen on an IP address make sure all ports are disabled/unchecked for the specified IP.

Hi Neill,

 

As you noted we do have IPv6 support in SmarterMail 11 and later and at this time we will not be adding any new features to SmarterMail 10.  You should still be able to use SmarterTrack and SmarterMail 10 event without IPv6 support.  At this time to further troubleshoot this issue we will need access to your server and this will require a support ticket.
