My email is taking for ever to send and receive. Any ideas? It's taking hours. to arrive. Even sending an email to myself, using webmail, takes forever. Then, after a few restarts, it will be fine again. Then it will slow down again. Please help.
As far as I can see, your server is trying to connect to that other server, not the other way round. You should check if your server is an open relay: http://www.spamhelp.org/shopenrelay/
I tried the relay test and it said Code: Error - could not connect to server All of the emails were coming from [email protected], so I updated ISPConfig. It seems to have worked so far.
