[Dovecot] dict quota not being updated for all users when receiving a multi-recipient message

[Justin McAleer]

I've set up a mysql quota dictionary using the proxy setup as described 
in the wiki (using Dovecot lda). When I send a single message to 
multiple users, only the first recipient is getting their usage updated. 
This behavior occurs if I manually send to more than one user via the 
To: line, or via aliases set up in postfix. I do have 
dovecot_destination_recipient_limit set to 1.

I don't even have a guess as to what might be going on here, since each 
instance of the lda is a separate process. But, let me know if anybody 
has any ideas or requests for more info.
