Thanks for your and the other suggestions. I will try them in the next
days. As the server is productive I can change essential settings only
outside working hours in a small time slot.
I'm just wondering why my other mail clients can send mail with SMTP
authentication and RC doesn't? But maybe RC needs mandatory the SMTP
AUTH banner in the smtp dialogue?
Bye

This is what I have, which other than the port is basically identical:
$config['smtp_server'] = 'tls://mail.covisp.net/';
$config['smtp_port'] = 587;
$config['smtp_user'] = '%u';
$config['smtp_pass'] = '%p’;
$config['imap_auth_type'] = 'PLAIN’;
I do not have a timeout set for SMTP, so first suggestion is comment that out.
For postfix (3.4.8):
In master.cf I have:
submission inet n - n - - smtpd
-o smtpd_tls_security_level=encrypt
-o smtpd_sasl_auth_enable=yes
-o smtpd_sasl_type=dovecot
-o smtpd_sasl_security_options=noanonymous
-o smtpd_sasl_path=private/auth
-o smtpd_milters=
-o milter_connect_macros=
-o milter_macro_daemon_name=ORIGINATING
-o syslog_name=postfix/submit
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
-o smtpd_data_restrictions=
-o smtpd_relay_restrictions=permit_sasl_authenticated,reject
-o smtpd_helo_restrictions=
-o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
In main.cf:
broken_sasl_auth_clients = yes
smtpd_sasl_authenticated_header = yes
smtpd_sasl_path = private/auth
smtpd_sasl_type = dovecot
