Everything was working fine,until over the weekend. I can send emails without a problem but I have a problem receiving them. I also am unable to telnet bookowl.co.uk I get connection refused. But if I telnet the ip address 192.168.*.* then I can do a ehlo and everything seems fine. I can also telnet from my laptop and both the domain name and ip are accepted. The hosts file looks ok 127.0.0.1 localhost.localdomain There are no errors showing in the maillog file except that when I log on there is a delay of around 6 mins before a message is placed on the lmaillog saying that I have been disconnected because of inactivity.
