I have some monitoring scripts on a couple of servers checking stuff that's not too critical (but that I indeed would like to receive email alerts for).
I use Postfix and my SMTP-to-SMS email address so that I can receive these notification on my cell phone. My problem is: I don't want to receive these alerts at dawn when I'm sleeping :(
I know I could modify my scripts in order to accomplish this but I decided that the best way to do this is to change postfix (since it isn't being used for anything else). How can I make postfix "put on hold" all new "incoming" messages, let say from 11pm to 6am? And then later at 6am flush that queue?
