Hi all,

I would like to ask whether there is a way to postpone or delay message processing on postfix mail server. E.g. to postpone message transfer/relay for 5 minutes to be able to dequeue mis-targeted emails.

I couldn't find anything because these keywords mislead to performance problems.

Thank you in advance,

Regards,

Marek

You are correct, that trying to search for these keywords brings up lots of discussion of analyzing performance issues. I did find one, though, that may be relevant. Take a look at this link from the Postfix documentation. It looks like there are two parameters that can be used to control and insert the delay between messages. One caveat is that they may be oriented towards multiple messages to the same recipient domain. The document is large and contains a vast number of parameters. If these don't do what you would like, try scanning the document for words like delay, time, defer, and so forth. It looks there are some unique items and there may be one that will work. For example look at the default_recipient_refill_delay.

Thanks, I'll get to that during weekend and post back if I extract something useful.
