I have Postfix installed on a Fedora 38 box with the following:
$ grep smtp_ main.cf
smtp_sasl_auth_enable = yes
smtp_sasl_type = cyrus
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_always_send_ehlo = yes
smtp_use_tls = yes
smtp_sasl_tls_security_options = noanonymous
smtp_tls_wrappermode = yes
smtp_tls_security_level = encrypt
$ grep smtpd_ main.cf
smtpd_banner = $myhostname ESMTP
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = $myhostname
smtpd_client_restrictions = permit_mynetworks, permit
smtpd_recipient_restrictions = permit_mynetworks, permit_auth_destination, permit_sasl_authenticated, reject
# smtpd_use_tls = yes
smtpd_tls_cert_file = /etc/pki/tls/certs/arixserver.crt
smtpd_tls_key_file = /etc/pki/tls/certs/arixserver.key
smtpd_tls_session_cache_database = btree:/etc/postfix/smtpd_scache
and I'm trying to log into it like this, where the username/password was generated with something like perl -MMIME::Base64 -e 'print encode_base64("myvalue")
$ telnet mail 25

535 5.7.8 Error: authentication failed: UGFzc3dvcmQ6
I've read a lot of posts here and it is my understanding that authentication against the server is handled by Dovecot (so I'm guessing the smtpd_* info is relevant) and I know the username/password are correct because I can log into the host (using SSH) using them, and also:
$ testsaslauthd -u $USR -p $PASS
0: OK "Success..
why am I getting this authentication failure?
TIA -- ekkis
