That's a good alternative.My request about doing it with sieve was to mimick Sun JES/Messaging behaviour that sent the overrquota warning upon new message receipt (only once) or, in case of no incoming traffic, on user login (not with sieve in this case, obviously).On a multiserver deployment with specialised systems (cyruses on their own machine, postfixes on another, imap proxies on third systems), Merlin's suggested approach is not practical.So, dealing locally with the output of quota helper tool is still the way to go. Simple. Stable. Flexible. Available.Paolo

Paolo,
Attached is the script we've been using for ages for this purpose. Our 
uses LDAP as a source of user ID information, but it could be easily 
adapted for other AAA databases.


Cheers,

Is there a way to achieve the same result somehow, with stock cyrus?

Hi,

Quoting Paolo Cravero :

user that his quota is about to fill up through an email, triggered on new
mail arrival or login. Why? Because not all clients support reading the

We have a daily cron-job which checks the quota usage and informs
the user via mail if more than 85% is used. The scripts limits the  mails
send to each user to one every week. An other mail is send if 100%
usage is reached.

Two other ways i can think of is parsing cyrus logs, or using the  
notify daemon

There is no mailbox annotation that exposes quota that could be used with the mboxmetadata extension (RFC5490) and there is no current Sieve extension for checking quota.Thank you Ken.

You could do it with your MTA instead - you could write a filter/router/acl in 
exim for example - these can use arbitrary command output to decide on what to 
do with a message.

There is no mailbox annotation that exposes quota that could be used 
with the mboxmetadata extension (RFC5490) and there is no current Sieve 
extension for checking quota.

Re: Sieve RFC5490 checks user quota usage

[Nic Bernstein]

Paolo,
Please clarify; when you say "disk quota," do you mean a filesystem 
level quota, or do you really mean IMAP STORAGE quota, as administered 
through Cyrus?
