Hi all,
I noticed that in some circumstances quota warnings are ignored. The bug arises when both of the following are used:
1. percentage-based quota warnings, i.e.:
quota_warning = storage=1%% quota-warning 1 %u
2. filesystem quota backend (and probably others, except for quotas configured directly in dovecot config)
Percentage-based quota warnings have rule.bytes_limit recalculated based on root_set->default_rule.bytes_limit, however this value is zero when FS quotas are in use. Real quota values (from quotactl) are fetched very late, in quota_warnings_execute() but at that point no recalculation happens. As the warning rules have bytes_limit==0, they're effectively ignored.
The patch below enables quota warnings to be sent when using filesystem (and possibly maildirsize-based) quotas.
Based and tested on Ubuntu 14.04's dovecot 2.2.9.
Best regards, Grzegorz Nosek

Hi, I saw that new dovecot was released. Is the quota_warning has been improved ?
That patch is doing a bit too many recalculations, which also always trigger debug message logging if mail_debug=yes. The attached patch probably fixes the problem? I'll add it after v2.2.20 is released (because it's affecting so many different platforms that there's too big of a chance of it breaking one of them due to some typo).
