RE: Help with configuration?

1. I want to have incoming emails automatically placed in certain folders instead of 'Inbox' based on certain criteria. For example, I want all emails from PayPal to go into the 'PayPal' folder and all emails from the Debian mailing list to go into the 'Debian' folder. Can dovecot do this for me and what is the best approach?

2. When I delete an email using my user client, it is only 'marked' as deleted (Thunderbird places a scored line through it, and a 'T' is added to the filename in the Maildir). How can I get dovecot to automatically move mail marked 'deleted' to the Trash folder each time?

cron job with dovadm ?

I also want further delete operations on any mail in the 'Trash' folder to be permanently deleted.

cron job with dovadm purge?

3. I want to hide my client IP address from the headers when submitting mail to Dovecot's submissiond, but I can't seem to find any way to disable this. I would prefer that recipients only see the server IP address, but not the IP address of the mail client which submitted it.

I am using mailfromd on incoming and outgoing servers. You can easily remove headers with that.
