I'm trying to configure my sendmail to use a different mail host (relay
host) depending
on what the destination address is. The reason for this has to do with
our internal
security setup. I'm on a solaris 9 platform.

So if I have mail to send to xxx@abc.com I would like to use
mailhost1, and if I have
mail for xxx@anythingelse.com I would like to use mailhost2.

Do I have to modify the sendmail.cf manually by creating a private
Ruleset which modifies
the macro setting for what the mailhost is?

thanks for any .

I think what the other posters are saying is that the rules are static
and you can't change them on the fly, which you'd have to do with each
piece of mail. Sendmail can use different relays depending on the
domain of origin, but not what you want to do.

Use another MTA or perhaps enhance sendmail to do what you want (good
luck with that).

pkgrm sendmail. Add in Postfix, and use its transports table.

abc.com smtp:[mailhost1]

then set your normal relay host to mailhost2 in your main.cf

If you want to do TLS outbound connections, it can be controlled per
site in your tls_per_site config file.

PLEASE upgrade to Sendmail 8.13.6 before doin anything else

You will need to add a LOCAL_RULESET_0
in the M4 macro configuration. (
/usr/lib/mail/cf/cf/your_mc_file.mc )
note that there must be one TAB to separate the LEFT most string from
the the rest of the line.

--------------

LOCAL_RULESET_0

R$+<@abc.com.> $#esmtp $@[192.168.111.11] $:$1<@abc.com.>

----------------


in this example 192.168.111.11 is your MTA for sending mail to
abc.com


Then you can build the sendmail.cf file with your_mc_file.mc M4
macro as usual.

Wow, seems like there are several ways to solve this configuration
setup.
Thanks for the guidance......

However, our system does not have the sendmail.mc file we have a
main.mc and
main.m4 file and all the other m4 files as well in the
/etc/lib/mail/feature dir.


thanks again.

Please upgrade to sendmail 8.13.6 first.
this is SUN Patch 113575-7 for solaris 9


you can start with the " main.mc" file as a template
these four lines are the bare minimum for an MC file
copy these four lines to myfile.mc to begin with.

OSTYPE(`solaris8')dnl
DOMAIN(`solaris-generic')dnl
MAILER(`local')dnl
MAILER(`smtp')dnl

SUN has added a few lines extra in their main.mc file to make
sendmail always add the local domain name and to
make mail to be sent to a host with the alias mailhost

that makes sense as a default config.

run

# cd /usr/lib/mail/cf/cf
# /usr/ccs/bin/m4 ../cf/m4.cf myfile.mc > sendmail.cf

to produce the sendmail.cf file from myfile.mc MACRO file.

The documentation that comes with the source code is here:

http://www.sendmail.org/doc/


For more info you really really really really need the BAT book.

http://www.oreilly.com/catalog/sendmail3/

( since I wont retype the 1000+ pages of info )

No, the other posters are saying to use the mailertable, which is a
standard feature in the sendmail config. Static rules (using external
tables in this case, but that's not necessary) are just the thing you
want to be able to say "mail to domain foo should be relayed to host
bar, mail to domain baz should be relayed to...", right?

Actually for *that* there is no standard feature - you can write your
own rules or find a third-party feature on the net.

There may be valid reasons to replace sendmail with Postfix, but being
able to put the exact same information, with the exact same syntax, in
the "transports table" instead of the "mailertable" surely isn't one of
them. (Gee, wonder where Wietse got that idea...)

What have you got against 8.13.8 ?

Oh nothing , but the OP would have to compile it from source
which doesn't seem to be within his present capability
