I have a few problem users who mismanage their email accounts. As such, they are sonctantly filling up. When this happens, a rejection email is generated, but if it was generated from a spam, then the return address is likely firged anyway, so they are filling up in the queue, and probably a fair number being sent to people who never sent them anything.

Long story short, is there a way to get exim to check the quota prior to accepting delivery, kind of like we are with the spam score?

Thanks for any help you can provide!

Under WHM / Exim configuration Editor / under options section, below switch to advanced mode button. There is an checkbox to
'Discard emails for users who have exceeded their quota instead of keeping them in the queue.'

Yeah, that prevents the message from being stored in the queue, but the system generates a bounce email telling the sender that the box is full. I was hoping to have it to that at MTA time.

If the sender field is forged, the bounce message ends up sitting in the queue.

You can use Exim System filter file to igore these bounce being sit in the queue. If you post me the full header and body of the bouce message, I might come up with a solution.

Sorry for the delay, seems email notifies aren;t working and I forgot about this for a few days.

Anbyway, here is an example header:

Hi

You can do this under acl_check_rcpt:

##QUOTACHECK!
deny domains = +local_domains
verify = recipient
condition = ${run{/opt/exim/bin/eximquotacheck ${extract{Quota}{$address_data}{$value}} ${extract{Dir}{$address_data}{$value}}}}
message = $local_part: Quota exceeded - Mailbox full

/opt/exim/bin/eximquotacheck should be some kind of script which could check the users quota and return 0 if it's ok or 1 if it's exceeded...

Greetings
