Having issues with receiving mail to the server, I think its an issue with TLS. Not entirely sure but keep getting sasl authentication failed.

Yep it is. I've spent hours trying to fix this and don't understand what is going on.

this path should be "private/dovecot-auth". Do you have /var/spool/postfix/private/dovecot-auth?

I do have the file here yes.

root@mail:/var/spool/postfix/private# ls -al | grep dovecot-auth
srw-rw-rw-  1 postfix postfix    0 Jan 22 19:39 dovecot-auth

I read online to try this and it seems to authenticate, however inbound mail or outbound mail is not working.

root@mail:/var/spool/postfix/private# doveadm auth test xxx@xxxxxx.pw
Password:
passdb: xxx@xxxxx.pw auth succeeded
extra fields:
  user=xxx@xxxxxx.pw

Edit: I changed the line you mentioned and then reload'd postfix then dovecot and still seem to get error in mail.err log.

Re: RE: No SASL authentication mechansisms

Please turn on debug mode in Dovecot and try again, monitor its log file (/var/log/dovecot.log) to see why it failed.
Reference:
http://www.iredmail.org/docs/debug.dovecot.html

By the way, did you compile Postfix yourself? Or, modified any Postfix/Dovecot/... settings before this issue?
