Hello,
I'm attempting to configure SMTP authentication to permit
[authenticated] remote users to relay messages and I'm having very
little luck.
I started out with SASL, and later determined I was going about it the
wrong way, as it required a database (sasldb) of user names and
passwords. As all users already have a Unix login, I felt it was
redundant to provide them with a second account to keep track of.
Afterwards, I read more on saslauthd and realized that it was possible
to use PAM for authentication. So, if my understanding is correct, I
could theoretically use this method to check the local Unix account
names and passwords to verify validity. I'm currently using PAM to
authenticate Cyrus-IMAP with success. I just can't get it to work with
Postfix, to save my life!
My /etc/sasl2/smtp.conf file looks like:
# $Header: /var/cvsroot/gentoo-x86/mail-mta/postfix/files/smtp.sasl,v

#pwcheck_method
am
#mech_list: plain login
pwcheck_method: auxprop
auxprop_plugin: pam
/etc/postfix/main.cf has the following options (plus more):
smtpd_sasl_auth_enable = yes
smtpd_sasl2_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_sasl_local_domain =
smtpd_use_tls = yes
smtpd_tls_key_file = /etc/postfix/newreq.pem
smtpd_tls_cert_file = /etc/postfix/newcert.pem
smtpd_tls_CAfile = /etc/postfix/cacert.pem
smtpd_tls_loglevel = 3
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
If there is any information that anybody could provide for me, I would
greatly appreciate it.
Thank you much in advance,
