Description MarisN 2007-09-05 14:37:09 UTC
In postfix-2.4.3 if in virtual_mailbox_limit_maps user has quota 0 (zero) it means "unlimited" like for virtual_mailbox_limit or mailbox_size_limit. In postfix-2.4.5 quota=0 has turned to "Use default virtual_mailbox_limit" thus breaking any existing postfix virtual_mailbox_limit_maps that still assume 0=unlimited.

Reproducible: Always

Expected Results:  
Quota setting virtual_mailbox_limit_maps should act similar to mailbox_size_limit.

It's possibly is related to changes in VDA patch around line 848:

I'm experiencing the same problem after upgrading to 2.4.5 today

Postfix 2.4 series includes the new VDA-NG, a rewritten and improved version of VDA.
for an explanation of this particular change.
Basically it is a fix for incorrect behavior that VDA displayed in older versions. 
If you need unlimited quota for a maildir, set it to 0 explicitly for that email.
Best regards, CHTEKK.

Ahmmm sorry, misunderstood this one... Zero is actually indeed a logically valid value and is threated as not being one... I'll fix this in VDA.
Best regards, CHTEKK.

mail-mta/postfix-2.4.6 should fix this and revert the meaning of quota=0 to "infinite quota". I'd very much like to hear if this indeed fixed your Postfix use cases or if there still are problems...
Best regards, CHTEKK.

Ok I just finished all my tests and added mail-mta/postfix-2.4.6-r1 to the tree, which correctly fixes this also for mailbox quotas (and not only maildirs).
Best regards, CHTEKK.
