Hello me again,
After getting all sorted out the system is working but even doe while sending email is almost instantaneous, the reception of email is very slow, up to 90 minutes from the time the email is sent from a remote system to the time that is received and delivered to the mailbox by iRedMail.

I wonder if there is some sort of tuning that can be applied, all tests are from common email providers such as google,yahoo, outlook.com, netscape, etc...

Thank you
