Ok, but how can be syncronized the two vision of the quota, if only vpopmail uses vusaged ? I think that there can be only two cases 1) all tools use vusaged or 2) all tools use traditional Maildir++ quota. In any other combination, the two vision of the real maildir quota will go quickly out of sync. > >>> I've looked the code and found that there were no option to disable the > >>> usage. > >> > >> Turn off their quota and the vusage daemon shouldn't be looked at.

Yes, and this works, but it generate an error message each time the daemon is searched for. For a normal deliver, that means at least 3 error messages on the log file. And 3 attempts to open the socket. I think it's more efficent, and cleaner, to check if one wants to disable the daemon, adding a line in the config file. My patch just do that. Take a look at one line of my logfile: Sep 3 09:12:25 moss qmail: 1251961945.482023 delivery 35086: success: client_connect:_connect_failed:_2/client_connect:_connect_failed:_2/client_connect:_connect_failed:_2/client_connect:_connect_failed:_2/did_0+0+1/ Is only to avoid the repeated "client_connect:_connect_failed" string, and to retrieve some CPU cycle, that I've wrote the patch. -- Simone Lazzaris INTERACTIVE NETWORK SRL Via Roggia Vignola 9, 24047 Treviglio (BG) tel : +39 0363.302820 fax : +39 0363.304352 web : http://www.interactive.eu email : s.lazza...@interactive.eu
