Can you convert these to
*@domain1.com fred
jim@??? alias1
etc.?

you could use a router like this then:

virtusertable:
   driver = redirect
   domains = +virtual_domains
   no_more
   data = ${lookup{$local_part@$domain} lsearch*@ \
                {/etc/mail/virtusertable}}


Otherwise, the you'll have to use
virtusertable:
   driver = redirect
   domains = +virtual_domains
   no_more
   data = ${lookup {$local_part@$domain} lsearch \
              {/etc/mail/virtusertable}{$value} \
              {${lookup{@$domain} lsearch \
                {/etc/mail/virtusertable} }\
           }


replace lsearch with whatever databaseformat you use.

in the main section you should declare the domainlist virtual_domains,
which contains all domains that should be looked up from virtusertable
(I don't know how sendmail handles this)

aliases:
driver = redirect
data = ${lookup {$local_part} lsearch{/etc/mail/aliases}}

Read up about the manualrouter, and use a dataformat that is useable
with exim (you could also use this, but it will be a pain)

if it is only this single domain, you can use
somedomain_router:
driver = manualroute
domains = somedomain.com
route_data = some.other.mailserver.com

Read it again :)

Hmmm, well I don't know enough about sendmail to help, but if somebody
who knows more about it will send me some sample-files (if possible some
really sick ones) I'll give it a try and write up something.
