Does postfix require a restart after changing maximal_queue_lifetime ?

According to this article

Tuning Postfix Queue Settings - Zimbra :: Wiki

It says after changing maximal_queue_lifetime via postconf –e maximal_queue_lifetime=15m the changes takes place immediately.

My question is - postfix will have to be restarted for the changes to take effect right ?

[uxbod]

It should only require

su - zimbra
postfix reload

[priyadarsanroy]

Yes I was also thinking that should. I think some one needs to modifiy that wiki article to include that.

Since most Postfix daemons are short-lived, your new settings are actually recognized automatically as those daemons expire and new ones are launched. However, longer running daemons such as pickup, qmgr, and possibly trivial-rewrite will not detect changes to main.cf, so changes to parameters used by these daemons require that you reload Postfix. Changes to master.cf always require a reload. Note that with changes to the inet_interfaces parameter, a reload is not sufficient. You must stop and then start Postfix in this case. - Special thanks to Vi[ck]tor Duchovni for information in this answer.
