Hi everyone.

All worked fine. Then I added in dovecot.conf file: auth_mechanisms = plain login cram-md5 #added cram-md5 passdb { #args = /etc/dovecot/dovecot-sql.conf #driver = sql driver = passwd-file args = scheme=cram-md5 /etc/dovecot/cram-md5.pwd } In passdb block commented out default lines and add two (I can put whole dovecot config). All things still worked fine. Then - in dovecot.conf file I changed back setting to default. After this I can't send emails. In log I have: Feb 23 06:46:49 vps301 postfix/smtps/smtpd[24919]: fatal: no SASL authentication mechanisms Feb 23 06:47:50 vps301 postfix/smtps/smtpd[24942]: fatal: no SASL authentication mechanisms Thread on dovecot mailing list about this problem takes 65 sended emails. Still nothing. -- *Pozdrawiam / Best Regards* *Piotr Bracha* *tel. 534 555 877* *ser...@poliman.pl <ser...@poliman.pl>*
