What you will need to do is first modify sendmail.cf to deal with two
databases in the /etc directory that will handle the aliasing.
add these two lines to sendmail.cf
Kvirtualhosts btree /etc/virtualhosts.db
Kvirtualmasqs btree /etc/virtualmasqs.db
add this rule set for the return mail masq
S40
R$* < @ $* > $* $@ $1 < @ $2 > $3 already fully qualified
#bc instead of automatically using $M, lookup masquerade in virtualmasqs
R$* $: $(virtualmasqs $1 $: $1 @ $M $)
#bcR$* $: $1 @ $M add local qualification
R$* @ $: $1 @ $j if $M not defined
add this rule set for the virtual hosts
S98

for inbound mail:
create /etc/virtualhosts with your favorite text editor, there can be
as many lines as you want for each virtual host.
virtdomain.com john@mydomain.com (all mail goes to john)
sam@virtdomain.com sam@mydomain.com
webmaster@virtdomain.com bob@other.domain.com (forward mail to
third system)
create the database virtualhosts.db from virtualhosts with the makemap
command (makemap comes with sendmail)
makemap btree virtualhosts.db <virtualhosts
for outbound mail (they need an account on your system)
create /etc/virtualmasqs (if you use PINE do this in setup)
frank frank@virtdomain.com
gloria gloria@virtdomain.com
fred fred@virtdomain.com
create the database virtualmasqs.db from virtualmasqs with the makemap
command
makemap btree virtualmasqs.db <virtualmasqs
****************************************
EACH TIME YOU ADD ANOTHER VIRTUAL DOMAIN
****************************************
(this is from part of the instructions I give sysop's on our system)
5. Add Cw line in /etc/sendmail.cf
Cw new.domain.com
6. Add alias to /etc/virtualhosts
webmaster@new.domain.com account@real.domain
run command:
makemap btree virtualhosts.db < virtualhosts
7. if they have an account on our machine and want mail to look like it
is coming from their domain.
add alias to /etc/virtualmasqs
username anyname@new.domain.com
run command:
makemap btree virtualmasqs.db < virtualmasqs
8. restart sendmail
get the pid with
ps -aux | grep sendmail
run command:
kill -HUP sendmail.pid
