The delay on sending/receiving could be related to greylisting, do you have this enabled?
you didn't post any related log files so this is all only guessing

Sorry I'am new with iRedMail. Can you share what logs should i look at and how to manage greylisting?
Thank You.

Can't access on browser and error on mail client upon testing. It happens late this morning but I can access it early this morning. I don't know what happened. I did do anything on the server.

Upon checking today, its working again. I don't know what cause the problem. My second concerns it has delay on sending/receiving emails. Some emails will be received after one(1) day.
