I have a VPS server that runs postfix + dovecot as a mail server. I have already created two accounts that work well. Both can send and receive email through STARTTLS and SSL.
But when I added a third account today, it can only receive email, but could not connect the SMTP server. So this is not a problem with the wrong password. The SMTP settings are similar to the settings of two other accounts. Client settings must be correct.
The postfix log says:
Aug 28 12:55:32 server postfix/smtpd[1645]: warning: SASL authentication failure: Password verification failed Aug 28 12:55:32 server postfix/smtpd[1645]: warning: unknown[203.97.197.232]: SASL PLAIN authentication failed: authentication failure Aug 28 12:55:35 server postfix/smtpd[1645]: warning: unknown[203.97.197.232]: SASL LOGIN authentication failed: authentication failure
Sasl and tls settings in main.cf:
smtpd_sasl_auth_enable = yes smtpd_sasl_type = cyrus smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_authenticated_header = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_tls_auth_only = no smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom
Can anyone help me out?
Many thanks.
