dovecot - Jun 2008 - quota-rewrite patch & userdb quota overriding

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I've spent the past couple of hours trying to figure this out by
checking the wiki and googling, but haven't come up with anything that
works yet.

I just installed dovecot 1.0.14 with the quota-rewrite (1.09) patch and
i'm trying to get the quota overridden via a passwd-file type userdb.

I had 1.0.13 without the new quota style patched in working but having
trouble figuring this out. any help would be appreciated.

prior to the quota-rewrite patch (which i installed with the hopes of
using quota_warn feature) i was able to put the following line into my
passwd-file userdb and it was working:

alan:*:1000:1000::/home/alan::userdb_quota=maildir:storeage=2048000:ignore=Sent

(which is what I wanted) but now with the new quota definition style,
I'm not sure what I need to define the extra fields as.

here is dovecot -n:

You'll most likely want to override quota_rule, so:

?alan:*:1000:1000::/home/alan::userdb_quota_rule=*:storage=2G

The rest can be kept in:

plugin {
  quota = maildir
  quota_rule = *:storage=1G
  quota_rule2 = Trash:storage=100M
  quota_rule3 = Sent:ignore # well, this works only with v1.1 actually
}

Timo,

Cheers, that sorted me out.  Now I have a different problem I've been
trying to workout with quota_warning.

it appears that dovecot is reading the quota_warning settings properly
and calculating the threshold properly[1] but for some reason it doesn't
appear to be executing the command I've set.  I'm trying to run a perl
script.  looking at the quota_warning code it doesn't appear that that
would be a problem, and if it was it should return an error, which i'm
not seeing in the logs so i'm not sure what's happening at this point.


[1] here's some log data:

if the account is actually over quota, deliver properly rejects the mail
with Rejected: Quota exceeded.

any ideas where to look?  Also, it's not really clear what the command
passed to quota_warn actually needs to do.  in one post by the original
creator of the quota_warning plugin (sorry, I don't recall their name)
it looked like they just piped the output of an echo command to deliver
- -c /path/to/alternate/dovecot/conf/without/quota_warning/settings .

I've tried, that.. I've tried just having it write data to a file in
/tmp .. neither of these techniques generate any results so I can only
assume that it's not being executed.

Thanks in advance.

Alan
