I upgraded my email server to 0.9.3 by following your guide. (no problems so far)
But after installing and reboot from server i suddenly don't have access to my webmail.

If i do a Telnet command it does not respond on port 80.
For port 143 there is no problem there.

The strange part is when i reboot again -> and i do telnet 80 -> i have response.
but after 5 minuts it's not working.

Yesterday i installed roundcube to the latest version. (1.1.4) and it was working like a charm.

Today i finised my upgrade process and iredmain pro 2.2.0.

Can i have some idea's where to look. Thanks for your help

kind regards,

Kris
