SquirrelMail Login - login.php pop-up

[eko_taas]

On my (once again re-installed) test-setup Debian Squeeze SquirrelMail Login acts bit strange (to me).

I have web-server example.com (no SSL) and mail-domain example.com

I have followed 20.2 (but stopped before virtual host not made)
http://www.howtoforge.com/perfect-se...ispconfig-3-p6

What is working (i.e. going to login page was not working before 20.2)
- ISPConfig3 quick-link from email - mailbox e.g. "http://www.excample.com:8080/mail/webmailer.php?id=1 goes to http://server1.excample.com/webmail/src/login.php
- any link http://XYZ.example.com/webmail or just AYZ.example.com/webmail (XYZ can be anything :-)

But If I enter only domain name
- http://excample.com works (www page)
- http://excample.com/webmail

I'l get new window with

You have chosen to open
which is a: application/x-httpd-suphp
from: http://excample.com
What you want to do with this file ......

Not a biggest thing, but if someone uses webmail and get that message, does not look nice...

Any advice what to check?
