Hi benny,
Thanks,
That's exactly what i have in postfix:

smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes

plus:
smtpd_sasl_local_domain = fastmail

but the user that i have in the table, that worked with Cyrus, in the
format: "username at fastmail", it's not working with dovecot

meanwhile i was thinking, the auth is beeing made into the main table... i
just figured it out now!
How could i have the auth for dovecot SASL in a different table? I'd like to
keep having one sql table for imap/pop3 auth, and another for smtp,
This gives me the advantage of blocking only the outgoing emails for the
users, in case if a password is caught, which is very handy at least for me
as sysadm
