I have this in my main.cf (note: i didn't set this up, my guess is that debian itself did, or maybe when i installed libsasl2-modules, but i don't think so)
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls = yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache This is the rest of the relevant content in main.cf myhostname = helpdesk.ourdomain.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = helpdesk.ourdomain.com relayhost = [exchangeserver.ourdomain.com] smtp_sasl_security_options = smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl/sasl_passwd broken_sasl_auth_clients = yes smtp_always_send_ehlo = yes I tried then: smtp_sasl_tls_security_options smtp_sasl_mechanism_filter = login But if i do the last line, then it says NTLM isn't allowed. What am i missing to enable TLS properly and then be able to use AUTH LOGIN? -- View this message in context: http://postfix.1071664.n5.nabble.com/Exchange-2007-gives-535-5-7-3-Authentication-unsuccessful-tp65072p65121.html Sent from the Postfix Users mailing list archive at Nabble.com.
