CentOS - Nov 2007 - How to delete mails in the mailq in ONE DAY -- POSTFIX

I am runnig posfix on Centos 4.4 as a Mailgateway. It only accepts mails for
domains and then forwards mails to Lotus domino Server.

All clients sends outgoing mails to that Lotus domino Server. Then , That
Lotus Domino Server sends mails to Postfix mailgateway. This postfix
mailgateway sends mails to all the destinations. But, This Postfix
mailgateway has about 150 messages in the mailq. Some are unwanted mails. I
think they keep trying until 5 days old. I want decrease it to ONE DAY.



In Sendmail, this can be done by editing sendmail.mc  as below.


(`confTO_QUEUERETURN', `5d')dnl

changing above line to below line

(`confTO_QUEUERETURN', `1d')dnl


How Can I do it in Postfix?


ANY IDEA?




O Timeout.queuereturn=5d

It should be one of these:

bounce_queue_lifetime = 1d
maximal_queue_lifetime = 1d

These messages are not harmfull, and you should keep your setting to 5 
days.  You'll thank you when your domino server stops accepting messages 
for some reasons for 25 hours or more... it can happen...

do not accept mail to inexistent addresses. implement proper recipient
validation. if you can't share the list of users with postfix, then use
reject_unverified_recipient (only for recipients of your domains).

accept then bounce (backscatter) is no more acceptable.
