I changed some quota options in my dovecot config (eg. excluded folders) but afaik this only affects new mail and there is no magic command to recalculate the quota (or is there?). So I wrote this little python script to do this, maybe someone finds it useful.

It can output the sql statements (dovecot 1.0/1.1 and 1.2 format) or just print out quota usage to console.

Example mysql output,dovecot 1.2 format: # quotasync.py -o mysql -a user@domain.com INSERT INTO quota (username,bytes,messages) VALUES ('user@domain.com',47963905,6441) ON DUPLICATE KEY UPDATE bytes=47963905,messages=6441;

Example mysql output, dovecot 1.1 format, Spam folder excluded # quotasync.py -o mysql -a user@domain.com -d 1.1 -e .Spam INSERT INTO quota (username,path,current) VALUES ('user@domain.com','quota/messages',3982) ON DUPLICATE KEY UPDATE current=3982; INSERT INTO quota (username,path,current) VALUES ('user@domain.com','quota/storage',31811740) ON DUPLICATE KEY UPDATE current=31811740;

You can pipe this output directly to mysql. eg.: quotasync.py -a user@domain.com -o mysql | mysql yourdatabase
