deliverquota(8)

NAME
deliverquota - deliver to a maildir with a quota

SYNOPSIS
deliverquota [-c] [-w percent] maildir quota

DESCRIPTION

deliverquota is a temporary hack to implement E-mail delivery to a maildir with a software-imposed quota. This refers to a manually-enforced quota mechanism described in maildirquota(8), NOT a filesystem-based quota. If your current mail server does not support the quota maildir extension you can use this temporary utility. Instead of instructing your mail server to deliver the message to a maildir, instruct the mail server to deliver the message to the deliverquota program, and specify the location of the maildir, and its corresponding quota, as the arguments.

deliverquota reads the message from standard input and delivers it to maildir, which can actually specify a maildir folder. quota is a list of comma separated quota specifications. A quota specification consists of a number followed by either 'S', indicating the maximum message size in bytes, or 'C', maximum number of messages. For example:
deliverquota ./Maildir 5000000S,1000C

This delivers to ./Maildir with the quota set to 5,000,000 byes or 1000 messages, whichever comes first.
deliverquota ./Maildir 1000000S

This delivers to ./Maildir with the quota set to 1,000,000 bytes, without limiting number of messages.

The -c option causes the maildir, and all parent subdirectories, to be created if necessary (as 'mkdir -p'). This option should be used with caution.

The -w option causes a warning message to be delivered into the maildrop if the message was successfully delivered but has left the user over percent utilisation. The warning message is copied verbatim from /etc/courier-imap/quotawarnmsg with the addition of Date: and Message-Id: headers. The warning is suppressed if one was delivered within the last 24 hours.

RETURN CODE
deliverquota delivers the message to the maildir and terminates with exit code 0 if the message can be delivered without going over quota.

If the maildir is over its specified quota, deliverquota terminates with exit code 77 (EX_NOPERM).
