Hi.

I've got a Linux server running Apache httpd.
It does virtual domains without separarate IP's quite nicely.
What I want is virtual pop and shell services.   I've seen a
virtual pop setup that required separate IP's for each domain.
I'd like to be able to do it without separate IP addresses.
I'd like the user to log in (for pop and telnet) as user@domain
and have the daemon map that to the real account.
i.e. if I host acme.com and spam.com, and each has an email for
sales@acme.com and sales@spam.com, when the user telnets to the
site for shell access, they log in as sales@acme.com and it
maps to the unix account 'acsales', while sales@spam.com maps to
'spsales'.  I'd like the same for POP.
Lastly, I'd like to be able to have www.acme.com/~sales and
www.spam.com/~sales go to the public_html of acsales and spsales
respectively.
Anyone seen this done already?  I did metacrawler and dejanews
searches and checked the inet-access mailing list and didn't come
up with anything.
