Hi guys, I'm quite new to Plesk since I bought a VPS with it just few days ago. I'm trying to get my head around all the features of this rich Control Panel and all is going quite well, apart from few bumps here and there. I'm writing in this forum with the hope that someone will be able to help me out. From the general Settings it looks like I have two webmail modules installed: AtMail (1.04) and Horde (4.3.9). I have added a domain under the only Customer I have and I have pointed the actual domain name to the server. All working fine. I can see the website working. I have then created an email account under this domain (test@[domain].com) and the email is working if I set it up in my local mail client. Then, in the Control Panel I have clicked on the Mail tab, I have checked the settings of the email account and Horde is the webmail software selected in the list. Lastly I have clicked on the webmail icon of the email account. This opens a new window with this url: http://webmail.[domain].com/imp/login.php?new_lang=en_US&imapuser=heart%40[domain].com Where [domain] is my domain name. In that window I get a nasty "Server not Found" message. Does anyone know what is going on? It looks like Horde is not working at all. Is it a setup problem? Plesk? The hosting company? The VPS is brand new, has just been set up. Thanks a lot in advance for any help.
