[Dovecot] Variable expansion in LDA vs POP/IMAP

[Stephane Enten]

Hello all,

I'm trying to understand when exactly the variable substitution
happens in Dovecot, as I get different results in the LDA and in the POP/IMAP 
server.

Here's my general setup:
 - Postfix MTA, delivers mail via Dovecot LDA
 - users list sits in a database 
 - mail directory is stored in the database, but with
   Dovecot variables inside

Delivery works perfectly fine, Dovecot's deliver get a "mail"
column from the database (that looks like this: 
/mail/01/%2LMd/%2.2LMd/%LMd/mail/%Ln/ ) and expands variables,
delivers the mail into the maildir's location.

Now if I try to access the mailbox through Dovecot's POP/IMAP server,
it looks like it gets the right field from the database, but won't expand
the variables:

May 24 18:31:14 mail1 dovecot: imap-login: Login: user=<XXXXX>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured
May 24 18:31:14 mail1 dovecot: IMAP(XXXXX): Effective uid=1021, gid=304, home=
May 24 18:31:14 mail1 dovecot: IMAP(XXXXX): maildir: data=/mail/01/%2LMd/%2.2LMd/%LMd/mail/%Ln/
May 24 18:31:14 mail1 dovecot: IMAP(XXXXX): maildir: root=/mail/01/%2LMd/%2.2LMd/%LMd/mail/%Ln, index=/srv/mail/01/%2LMd
/%2.2LMd/%LMd/mail/%Ln, control=, inbox=
May 24 18:31:14 wmail1-v dovecot: IMAP(XXXXX): Disconnected

Am I missing something to get the pop/imap part expand those ?
