Hi,
My problem:
I can send email to external destination.
I can't received any email from external.
I have an error message:

mail.log:
May  1 15:47:23 servmail postfix/smtpd[3516]: NOQUEUE: reject: RCPT from mailclean.barracuda.com[XX.XX.XX.XX]: 450 4.7.1 <jean.bon@monserveur.com>: Recipient address rejected: Access denied; from=<victoria.qi@pdl-ma-ass.net> to=<jean.bon@monserveur.com> proto=ESMTP helo=<mailclean.barracuda.com>

mail.err:

May  1 15:06:21 servmail postfix/smtpd[2739]: fatal: no SASL authentication mechanisms
May  1 15:08:47 servmail postfix[2904]: fatal: usage: postfix [-c config_dir] [-Dv] command

auth.log:

May  1 15:55:58 servmail postfix/smtpd[3682]: auxpropfunc error invalid parameter supplied

May  1 15:55:58 servmail postfix/smtpd[3682]: _sasl_plugin_load failed on sasl_canonuser_init for plugin: ldapdb



For the test, fail2ban and iptables are stopped.

With this config, i can't received and send any messages:

All mailboxes are created (170) and roundcube and irmailadmin are ok.

Have you a sugestion or config type ?

Thank you for your help.

Re: Emission : Ok, Reception : KO

Two mistakes in Postfix main.cf:

1) smtpd_sasl_type must be set to 'dovecot' (without quotes).
2) smtpd_sasl_path must be set to './dovecot-auth' (without quotes).

After you fixed them, please restart Postfix service and try again.
