Hi all, I would like to ask does Postfix has some local delivery delay parameter to set? Let's say delay for 1 second per each message id in qmgr. For example, if an user send a mail to 70 ncrpt (number of recipient) at a time, Postfix will handle it as two seperate message and queued at qmgr by default. The first queue is ncrpt = 50 and the second is ncrpt = 20. It is because by default, default_destination_recipient_limit = 50. But this two message queue will deliver most at the same second, I would like to just slightly delay the second message id delivery 1 second later than the first one. Because I have some performance issue on the recipient authentication when the ncrpt of the original message is large (i.e. 200), if such delay can be made, it can free up the load to the authenication server and then I assume can relax the performance heavy duty a little. Thank you very much!
Yours Sincerely, Jacky, Hoi Kei Chan.
