SASL authentication failed
relay=smtpauth.rollernet.us[208.79.240.5]:2525, delay=0.85, delays=0.01/0.01/0.83/0, dsn=4.7.0, status=deferred (SASL authentication failed; cannot authenticate to server smtpauth.rollernet.us[208.79.240.5]: no mechanism available)
The rollernet help page has the following:
All clients must submit messages to smtpauth.rollernet.us on port 25, 2525, 587, or 465. Port 465 always runs in SSL mode for some clients (such as Outlook Express) which expect unconditional SSL. Ports 25, 2525, and 587 may use TLS or unencrypted connections. We recommend using TLS with port 587 for maximum security and portability.
Any ideas on what to do next?
