[Dovecot] mail_uid and mail_gid are not set in environment (for expire-tool and so)

[Baptiste Malguy]

Hello,

I've just subscribed to the list, as a recent user of Dovecot (1.2.4 by
now).

I eventually missed a point, so I tried to find other doc or comments about
my issue, but failed to. If the following has already been discussed, please
simply reply with a URL to the corresponding thread or doc ;-)

Now that I have covered my ass, here is the problem I meet.

In dovecot.conf, I have the following:
  mail_uid = vmail
  mail_guid = vmail
which is confirmed with 'dovecot -n'

I have a script my-expire-tool-test containing:
  #!/bin/sh
  set
which basically only display environment variables.

When I run :
  /usr/sbin/dovecot --exec-mail ext my-expire-tool-test
I do not see any variable MAIL_UID nor MAIL_GID. As a consquence, when I run
  /usr/sbin/dovecot --exec-mail ext my-expire-tool
with my-expire-tool containing:
  #!/bin/sh

  # This script is a workaround for Dovecot 1.2 having issue to load modules
when running expire-tool.
  # More information: http://wiki.dovecot.org/Plugins/Expire, search Dovecot
v1.2

  MAIL_PLUGINS=${MAIL_PLUGINS//antispam/}
  MAIL_PLUGINS=${MAIL_PLUGINS//imap_acl/}
  MAIL_PLUGINS=${MAIL_PLUGINS//imap_quota/}
  MAIL_PLUGINS=${MAIL_PLUGINS//mail_log/}

  exec /usr/lib/dovecot/expire-tool "$@"

It politely tells me:
  Error: userdb(user at domain) didn't return uid and mail_uid not set

Actually, this is this message error that lead me to check the environment
variables. Then I also checked the source code, and run:
  grep -r  env_put .  | grep -i mail_

No trace of mail_uid nor mail_gid. Did I find a bug or did I miss a point ?

Regards,
