|
|
|
+# limits, you can set/override them by returning "quota_rule" extra field
|
|
|
+# from userdb. It's also possible to give mailbox-specific limits, for example
|
|
|
+# to give additional 100 MB when saving to Trash:
|
|
|
+
|
|
|
+plugin {
|
|
|
+ #quota_rule = *:storage=1G
|
|
|
+ #quota_rule2 = Trash:storage=+100M
|
|
|
+
|
|
|
+ # LDA/LMTP allows saving the last mail to bring user from under quota to
|
|
|
+ # over quota, if the quota doesn't grow too high. Default is to allow as
|
|
|
+ # long as quota will stay under 10% above the limit. Also allowed e.g. 10M.
|
|
|
+ #quota_grace = 10%%
|

|
