I managed to set up my first Debian mail server using postfix and dovecot. I use roundcube to access my IMAP accounts which are defined by virtual users in a MySQL data base.
Everything works perfectly so far. What I want to do now is fetching mails from other servers (like hotmail for example) and distribute them to according virtual accounts.
Since I have absolutely no idea where to start here I thought I'd give it a try and just aks for a general direction.
Any help is much appreciated.
