[maximatt]

hi...

i not undestand this plugin (quota) , because if i set a value 10240 (like
in example) when i send a 4 messages with attaches sizes like 4MB they do
not nothing, but if i want to send a message like 12MB the dont me do that,
but in the first way the user inbox  have like 20MB.   ¿:(?


i have these settings for this plugin:

protocol imap {  mail_plugins= quota imap_quota }
plugin { quota= maildir:storage=10240 }

¿can anybody explain me that?  :(
