I have a setup that checks a file for the quote size and I then use a MySQL backend with virtual users. Here is a snippet of what I currently have:
maildir_format
maildir_tag = ,S=message_size
maildir_use_size_file = true
maildir_quota_directory_regex = ^(?:cur|new|\..*)$
current_directory = /
quota = ${lookup mysql{SELECT quota FROM horde_users WHERE user_uid="${local_part}@${domain}"}{${value}999}}
quota_warn_threshold = 90%
quota_is_inclusive = false
quota_warn_message = "\
To: $local_part@$domain\n\
Subject: Mailbox Approaching Size Limit (90% Usage)\n\n\
Please note that your mailbox is approaching its limit. Upon receiving this message, your mailbox was at 90% of capacity.\n"
However, please note that the "quota_warn_threshold" is set to an equal number as noted above.
Sometimes a user receives a very large e-mail that puts them over their quota limit. Does anyone know of a way to set it so that if the value is at 90% or GREATER, the message is sent out?
In addition, once the individual has reached their quota limit, is there a way that a message saying "your mailbox is now closed" can be sent out? I know that in an Exchange environment, that is possible.
I just have a few users that complain that they don't get the notice their mailbox is at 90% capacity and don't know that e-mails are bouncing because they have reached their limit.
