AW: Creating a backup of incoming mail

[Patrick De Zordo]

Well, I'll give you some configuration hints..

1. don't forget to install sieve (eg. "apt-get install dovecot-sieve")..

2. Add to "postfix/main.cf" the following lines:
---8<--------------------------------------------------------------------------------
# Tell postfix to hand off mail to the definition for dovecot in master.cf
virtual_transport = dovecot
dovecot_destination_recipient_limit = 1
---8<--------------------------------------------------------------------------------

3. In "postfix/master.cf":
---8<--------------------------------------------------------------------------------
# Integration with Dovecot - hand mail over to it for local delivery, and
# run the process under the vmail user and mail group.
dovecot      unix   -        n      n       -       -   pipe
  flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/dovecot-lda -d $(recipient)
---8<--------------------------------------------------------------------------------

4. add "$mail_plugins sieve" to "dovecot/conf.d/15-lda.conf"

That’s all! Then just provide the sieve scripts at location specified in "dovecot/conf.d/90-sieve.conf" and you are done!

Good luck!

Bye!
