Hi all? I want restrict some user to use POP3 and some other to use SMTP. I consider to startup multi Auth daemond and each use a diffenent SQL. For example: for pop3? select .... where pop3_service=1 and ... for smtp: select .... where smtp_service=1 and ... I don't know if this is a good idea and how to setup dovecot to do so. Is there any suggest? Thanks! -- Xueron Nee <xueron at gmail.com>
