we use Kerio Connect as a mail relay / gateway. No user mailboxes etc.
There is always about 5 minutes delay before the email arrives to the recipient (appears in gmail let's say).
The few minutes delay happens after "Result: relayed, Status: 2.0.0" is shown in Kerio Connect logs.
Receiving emails by Kerio Connect is pretty quick though.
Anyone else facing this issue? What could be the cause?

Once the server has sent the mail (relayed) any delay is down to the receiving mail server so out of your hands

Not sure if the problem I am having is related but I thought I would chime in. When I send email through Kerio Connect over our main cable Internet line, it works fine and sends fast. However, I am trying to set up a CradlePoint device with an AT&T SIM card in it as a backup in case our main cable Internet goes down. When I try to that it connects and receives a greeting from the client. But when it tries to send the body of the message, it will try for about 5 minutes before it eventually times out. In my case it never actually sends. But the fact that it tries to send for 5 minutes and you mentioned it takes about five minutes to send an email made me think it might be something related. I have been working with AT&T for about six months and they are scratching their head trying to find out what is going on.
