I have a few users that are often hit by a trojan virus that steals e-mail user and password. Having a very little (if not null) power on their machines, I need to be able to block the outgoing mail wich is handled by postfix via dovecot SASL. Blocking it at dovecot level would be optimal, for the virus doesn't necessarily use the e-mail of the user as its from, just the user and password for the authentication phase.Is it feasible?
not sure what you try to achieve * if you cahnge the pwd SASL auth is taken away * if you don't want enforce SASL per IP mynetworks is your friendbut nobody really wants to place foreign machines in mynetworks and allow to send mail unauthenticated from a machine he don't own - and if it si only because in most configurations more restrictions than with SASL are bypassed
it's anyways not a dovecot question
