Hi, I am new to Postfix.
I am trying to get Postfix to relay via mail.authsmtp.com. I have added the following lines to main.cf relayhost = [mail.authsmtp.com] smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous I get the following errors: warning: SASL authentication failure: No worthy mechs found SASL authentication failed; cannot authenticate to server mail.authsmtp.com[62.13.128.189]: no mechanism available I have run saslfinger -c (as advised in a previous post to this list), and have copied the output below this email. Any help would be gratefully received!
