Hi Nikita, thanks for the help, but I don't have any problem with
bouncing the mail after the deliver (in fact, the mail pass two MTAs
servers before reaching the final storage)
I will try (with my limited english) to explain it better. Now I m
working with a single quota rule for everyone. What I need is a
mechanism to give a custom quota to each user. I thought that a flat
file will be the simple and easy option to implement, and then use
"quota=${lookup {$local_part} lsearch .....}" in the exim transport. I
need a way to configure dovecot to follow the same file (or at least a
modified copy). I've been told on this list that I can't rely on the
maildirsize file, because it can be deleted under some conditions... so
i neet to stablish quotas to dovecot somewhere else.
My question is: can dovecot get a custon quota for a user from a file
(not sql or ldap) and use at the same time pam as userdb?
Thanks, Juan.

Hi, Im using dovecot with maildir++ quota and I have this problem, maybe
some of you already solve this and can helpme.
I want to use some flat file to tell exim and dovecot the quota limit
for each user, i tried to work with exim and maildirsize file, but exim
just ignores the limits there.
I need a way (a really simple one, i dont want to create a database or
an ldap server just for this) to tell exim and dovecot to lookup some
file to get the quota limits. I know how to doit with exim, now i need
to know how to tell dovecot to read the quota limits from this file. I
know that dovecot can read the quota limit from the userdb, but im using
pam and i dont want to change the entire auth schema.
Can I configure dovecot to get the quota limit from a file using pam as
userdb?
Thanks, Juan.

Try to google "exim smtp-time quota bounce". This is what you need.
Exim can't do rcpt acl quota checks from the box, thus you need:
1)Some external script which will periodically create overquota file\database
of users and reject them at smtp-time using lookup
2)Or write perl-script and exec it in router stage. Script will open
maildirsize file, count quota and gives you 'yes\no'.
Also you need to deliver via dovecot deliver. This scheme will work.
