Topic: How to speed-up iRedMail incoming message delivery?
When we were using 3-rd party e-mail service (running the same or similar stack of software), incoming messages were delivered in a matter of seconds. Now with iRedMail (running on a powerful dedicated server with a wide channel and near zero load) it takes minutes. What can be the reason and how to optimize this?
Users call me to complain that mail is not working as they expect to get a message in a matter of seconds after a sender tells them (by phone) it is sent.
