Scheduled sent

[Felipe Neuwald]

Hello Folks,

have a way that I can schedule the sent of e-mails?

I need that all messages that goes to my server between 8 AM to 8 PM at
work days go to deferred queue, and send them automatically at
non-work-days and non-work-hours.

Thanks,

Cron job at 8 AM:

postconf -e defer_transports=3Dsmtp
postfix reload

Cron job at 8 PM:

postconf -e defer_transports=3D
postfix reload
postfix flush

You might want to omit the "postfix flush" command. The mail will
eventually be sent anyway. Also, it might not be enough to defer
the smtp transport, depending on your setup.

Does the OP want to hold inbound mail also? Perhaps the employer does not
want people to get new mail in the middle of the business day. Does the O=
P
want to hold outbound mail? Magnus gives correct advice for delaying
outbound mail. To delay all mail enable the HOLD restriction at 8AM and a=
t
8PM disable the "HOLD" restriction and run "postsuper -H ALL".

As for flushing, it is a reasonable idea. Make sure you have recipient
validation in place if you are holding outbound mail, all those dictionar=
y
attack bounces will clog the queue even more when delayed.
