[Pkg-exim4-users] autosave sent mail in virtual user's maildir sent folder

[Rieker Flaik]

Hi,

to get away from freemail-providers in the long term, I set up a
vserver. At present, exim4 is working with dovecot-imapd and sa-exim.

There are virtual email-user-homes in /var/mail/vmail/$USERNAME/
(maildir) and they receive mail through exim4 and dovecots "deliver"
program. Outgoing mail is also handled by exim4. It's used as a
smarthost and offers "plain" or "login" (through TLS) to authenticate.

Please see below for appropriate config snippets.

Now I would like exim4 to autosave sent mail in virtual user's sent
folder. But how?

I know that email clients can be configured to save sent mail to a
specific location, but I would like this job to be done by exim4.

I hope someone out there could help me. Please do :)


 Thanks a lot,
   Rieker
