[Dovecot] deliver rewrites envelop-sender

[Ralf Becker]

Hello,

we are currently using sendmail, procmail, uwimap and qpopper. We are
planing to replace uwimap and qpopper with dovecot. Which seems to be a
very good idea :-)
But: Sendmail and Procmail will not be replaced.

Now I've realized that deliver rewrites existing "From <....> ..."
header lines to ">From <...> ..." and adds it's own "From "-line.

Example:
--------
My procmailrc end with
  :0
  | deliver -d beckerr

Mails are deliver to my INBOX, but

*  From beckerr at fh-trier.de  Sun Jan 07 17:37:43 2007
*  Received: ...
*  From: ...

is rewritten to

*  From MAILER-DAEMON  Sun Jan 07 17:37:44 2007
*  > From beckerr at fh-trier.de  Sun Jan 07 17:37:43 2007
*  Received: ...
*  From: ...

Is there a (simple) way to prevent deliver from doing so?

OR

In case "-f <envelop sender>" is not given, could deliver
1) read the envelop sender address from the "From <...>" line,
2) remove the line and
3) add it's own using the formally extracted sender address?

This sounds best for me and would cover the problem most effective...

BTW:

I've found the "dovecot deliver patch for procmail" and it looks really
good (http://dovecot.org/pipermail/dovecot/2006-July/014656.html), but
it seems to me, that the "From " line problem is solved by optionally
removing the whole line, so deliver would use it's own default "From
MAILER-DAEMON "-line ... and this in fact the problem


Regards, Ralf
