dovecot - Aug 2016 - custom mail_location detection for dovecot lda

Hi!

Is it possible to do something like "post-login scripting" to detect
and
set a per-user custom mail location for dovecot LDA delivery?

I tried to use a wrapper-script around dovecot-lda that sets the
environment variables MAIL="..." and USERDB_KEYS="MAIL" just
like
overriding userdb fields may be done using imap postlogin scripts, but
unfortunately this doesn't seem to be honored. (Also tried with
dovecot-lda -k.)

Woud be very useful for slow migration from one mailbox format to another.

Is there any other way to supply a custom mail_location to dovecot-lda?

Cheers,

You could use /usr/lib/dovecot/dovecot-lda -omail_location=<location>

There is probably a better way using a userdb though.

Thanks for the hint.
But it seems to be ignored. :-(
I tried it with a .forward of:

| "/usr/libexec/dovecot/dovecot-lda
-omail_location=maildir:~/Maildir:LAYOUT=fs"

and postfix logs:
... status=sent (delivered to command: /usr/libexec/dovecot/dovecot-lda
-omail_location=maildir:~/Maildir:LAYOUT=fs)

... but it still delivers to the default
(mail_location = mbox:~/mail:INBOX=/var/mail/%u)

Per-user configuration with userdb is static, you have to configure the
mailbox format for each user. However, if you'd like to give the user
the ability to switch between mailbox formats, dynamic detection would
be useful...
