Hi there, I've followed the perfect server guide for Ubuntu 11.04 (Still perfect the guide) and it can be a silly question but, my mail are working without problem by creating through ISPConfig an email and then, using Roundcube to log in. Working out of the box ! Great. But now, I'm testing Feng Office (Webmail) and it asks me the IMAP or Pop and SMTP server. No idea what to do... Thanks for your help !
Is this webmail application installed on your server? If yes, then the pop, imap and smtp servr is "localhost".
You will have to specify there the IP or fqdn of the mail server. For example: pop.yourdomain.com, smtp.yourdomain.com, imap.yourdomain.com But, before this, you will have to create that records in a DNS (a server in charge of manage the relation "domain = ip", or just add that reference to /etc/resolv.conf I can see that you are relatively new to this world so... if you want to learn more, look in google for topics like: dns basics, dns record basics, network basics, tcp/ip basics, mailserver basics, postfix basics, routing, switch, linux directory structure, etc. This world appear to be complex, but is more easy than it appears to be
