next in thread | raw e-mail | index | archive | help
I found this message in the archives and it was very useful to me, but I
still had some
problems getting sendmail to work so I modified this message with the
information
I used to get sendmail working for me. I'm using FreeBSD 2.2.6-RELEASE.
Remember
that sendmail.cf has a very sensitive sintax so do not forget to use
tabs for places where
you see more than one space between characters.
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.
1) Add these two lines to sendmail.cf
Kvirtualhosts btree /etc/virtualhosts.db
Kvirtualmasqs btree /etc/virtualmasqs.db
2) Add this rule sets for the return mail masq
S40
R$* < @ $* > $* $@ $1 < @ $2 >
$3 already fully qualified
R$* $: $(virtualmasqs $1 $: $1 @ $M $)
R$* @ $: $1 @
$j if $M not defined
S61
R$* < @ $* > $* $@ $1 < @ $2 >
$3 already fully qualified
R$=E $@ $1 < @ $j>
R$+ $: $(virtualmasqs $1 $: $1 @ $M $)
R$* @ $: $1 @
$j if $M not defined
3) Add this rule set for the virtual hosts
S98
################################
# sendmail for virtual domains #
################################
R$+ < @ $+ . > $: $1 < @ $2 > .
R$+ < @ $+ > $* $: $(virtualhosts $1@$2 $: $1 < @ $2 > $3 $)
R$+ < @ $+ > $* $: $(virtualhosts $2 $: $1 < @ $2 > $3 $)
R$+ < @ $* > . $: $1 < @ $2 . >
5) For inbound mail:
a) 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)
b) Create the database virtualhosts.db from virtualhosts with the
makemap
command (makemap comes with sendmail)
makemap btree virtualhosts.db < virtualhosts
6) For outbound mail (they need an account on your system)
a) Create /etc/virtualmasqs
frank frank@virtdomain.com
gloria gloria@virtdomain.com
fred fred@virtdomain.com
b) 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)
1. Add Cw line in /etc/sendmail.cf
Cw new.domain.com
2. Add alias to /etc/virtualhosts
webmaster@new.domain.com account@real.domain
run command:
makemap btree virtualhosts.db < virtualhosts
3. 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
4. Restart sendmail
get the pid with
ps -aux | grep sendmail
run command:
kill -HUP sendmail.pid
NOTE
If you only changed the virtual hosts and virtualmasqs databases you
do not need to restart sendmail!!!
