Using key authentication on a droplet, cannot get email server with SSL working

January 1, 2015 905 views

It almost looks as though authentication is happening from these few lines from /var/log/syslog but no sign of that at the client end. It's a Debian 7 system with the mail server set up from this tutorial and modified for Debian from here.

Can anybody out there offer some pointers?

  • That's telling me your client is attempting to authenticate with a plain SASL request, not a keyfile. How's your client configured?

  • Sorry, Starbs, hadn't realised I'd received a reply. So long ago I forgot what the actual solution was but it was something to do with an error in a line in a config file on the server, not an attempt at plain SASL request on the client.
