Let's assume a simple example: a mailing list where most of the recipients are at three domains: the local one (local.domain) and two remotes (one.domain, two.domain) and the rest is splittered over several other domains. For this case it is useful to specify three queue groups: QUEUE_GROUP(`local', `P=/var/spool/mqueue/local, F=f, R=2, I=1m')dnl QUEUE_GROUP(`one', `P=/var/spool/mqueue/one, F=f, r=50, R=3')dnl QUEUE_GROUP(`two', `P=/var/spool/mqueue/two, F=f, r=30, R=4')dnl QUEUE_GROUP(`remote', `P=/var/spool/mqueue/remote, F=f, r=5, R=8, I=2m')dnl define(`ESMTP_MAILER_QGRP', `remote')dnl define(`confDELIVERY_MODE', `q')dnl define(`confMAX_QUEUE_CHILDREN', `50')dnl define(`confMIN_QUEUE_AGE', `27m')dnl and specify the queuegroup ruleset as follows: LOCAL_RULESETS Squeuegroup R$* @ local.domain $# local R$* @ $* one.domain $# one R$* @ $* two.domain $# two R$* @ $* $# remote R$* $# mqueue
FEATURE(`queuegroup')
access.dbでqueuegroupを制御する
sendmail.mc に以下の2行を書きます。
FEATURE(`access_db') FEATURE(`queuegroup')上がaccess.dbを使うという設定、下がaccess.dbでqueuegroupに関する設定を 行う、という設定です。
queuegroup 2002
FEATURE(`queuegroup') FEATURE(`queuegroup', `default group')https://www.oreilly.com/library/view/sendmail-4th-edition/9780596510299/ch11s04s04.html
FEATURE(`queuegroup')
↓
Squeuegroup R< $+ > $1 R $+ @ $+ $: $>SearchList <! qgrp> $| <F:$1@$2> <D:$2> <> R<?> $@ R<$+> $# $1
FEATURE(`queuegroup', `localgroup')
↓
Squeuegroup R< $+ > $1 R $+ @ $+ $: $>SearchList <! qgrp> $| <F:$1@$2> <D:$2> <> R<?> $# localgroup R<$+> $# $1
The first line causes the queue group to default to mqueue if a queue group in the access database is missing or nonexistent. The second line allows you to set a different default queue group. For example, consider the following lines from an mc file:
QUEUEGROUP(`localgroup', `/queue/lq') FEATURE(`queuegroup', `localgroup')This causes sendmail to use the group named localgroup instead of mqueue as the default if a queue group in the access database is missing or nonexistent. Once you have enabled the FEATURE(queuegroup), the next step is to add lines such as the following to the source file for your access database:
QGRP:slow-poke.com slowgroup QGRP:root@notify.com fastgroup QGRP:your.domain localgroup
FEATURE(`queuegroup') QUEUE_GROUP(`mqueue', `P=/var/spool/mqueue/mqueue, R=5, r=15, F=f, Interval=1h') QUEUE_GROUP(`fast', `P=/var/spool/mqueue/fast, R=5, r=15, F=f, Interval=5m') QUEUE_GROUP(`cno', `P=/var/spool/mqueue/cno, R=5, r=15, F=f, Interval=15m') in access: QGRP:default mqueue QGRP:de fast QGRP:wichtig.com fast QGRP:auchwichtig.org fast QGRP:com cno QGRP:net cno QGRP:org cno
