Add:
FEATURE(`virtusertable',`hash -o /etc/mail/virtusertable.db')dnl
to /etc/mail/sendmail.mc
Then you can edit /etc/mail/virtusertable like:
sales@foobar.com bob@localhost
support@foobar.com alice@localhost
@foobar.com catchall_foobar@localhost
sales@barfoo.com tarzan@localhost
support@barfoo.com jane@localhost
@barfoo.com catchall_barfoo@localhost
This allows you to have complete namespaces for each domain. The only
issue is that you're underlying database (/etc/passwd) cannot have duplicates.
Ie if both foobar.com and barfoo.com want an account named cooldude. They
can't have it. They _can_ have an email address of cooldude@....
There are other options for mass virtual hosting but they all use databases
as the auth backend.

You can use /etc/passwd for the accounts database but you will need to keep a
seperate database of email address mappings.

... Why not imap. I know it is slow but it give you a world of flexibility.
I recommend TWIG as a webmail service. It's is fully customizable
and support virtual hosts. So foorbar's webmail can look different to
barfoo's. It also will NOT break POP access to the same mail box so it can
read mail however and when ever you like. Because the webserver talks to the
imapd you don't even need to make it network contactable just by localhost.
(Unless the mail and webservers are different machines)

Pass ... I would imaging that the sendmail webmin module can do what you
need, BUT I've never used it so I can't say for sure.
