temporary stopping remote delivery / php mail() when qmail stopped?

[Olivier Mueller <om-lists-qmail@omx.ch>]

Hello,

For cpu load reason, I'd like to generate some special mails during the
night, but send them "outside" only during the day.  Is there a way  
to stop
remote delivery for some time, while having the other qmail functions  
up &
running (smtpd & local delivery) ?  (dedicated server).

Otherwise what seems to work is to simply stop qmail completely  
(lwq's qmailctl
stop), and then send mails via the php mail() function.  Qmail is  
stopped, but
the mails seems to be stored correctely in the todo/ part of the  
queue, and
are delivered when qmail is started again. I don't know if it's the  
"good way"
to do it, but at least it seems to work... any comment? :-)

Other way I'm thinking about: create my own mail queue (simply a  
directory, with
one file per mail), and qmail-inject them when ready...

Feedback welcome! Thanks & regards,
Olivier
