Re: plain text authentication

It's mentioned in iRedMail-0.8.0 release notes:

All clients are forced to use IMAPS and POPS (via STARTTLS) for better security by default. To enable POP3/IMAPS without STARTTLS, please set disable_plaintext_auth=no AND ssl=yes in dovecot.conf.

Again, use STARTTLS for better security if possible.
