I've built Postfix 2.5.4 with Cyrus SASL 2.1.2 on a Solaris 10 05/08 Ultra 10. I've got SASL support in postfix since
[EMAIL PROTECTED] libpcap-0.9.8] 51 # postconf -A cyrus However, when I try to send mail it gets bounced by my ISP's server as no authentication is occuring. I've configured main.cf with the following: smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_sasl_type = cyrus relayhost = [outgoing.verizon.net] my sasl_passwd file is (with the username/password combination replaced): 54 # cat !$ cat /etc/postfix/sasl_passwd [outgoing.verizon.net] <username>:<password> The ISP server supports either PLAIN or LOGIN. I've manually verified that the username/password combination works by generating the base64 version of the combination and manually walking through the PLAIN authentication. The ISP does not accept connections on port 587 for submission -- I have to go through port 25. What I can't figure out is why Postfix doesn't send the AUTH PLAIN or AUTH LOGIN command to do authentication. Can anyone provide me with some fresh ideas as I'm all out.
