Hi,
I'm using sendmail for my email server.
I have 2 domain :
(1) abc.com
(2) xyz.com


My question :
1.How to configure sendmail for that 2 different domain using only 1 server?

Regards,
syzuhdi

Firstly you need to make sure that your server "answers" to both domains.

If you are "new" to sendmails lovely ~1000 line cf file I would advice you to use webmin and its sendmail plugin to easily and cleanly configure it.

If I find the place in my config I will get back to you later

a small example:


in DNS: abc.com mx 192.168.0.1
xyz.com mx 192.168.1.1

in sendmail.mc file search 127.0.0.1..... in this line change localhost(127.0.0.1) to 192.168.0.0(that means sendmail is listening for 192.168.0.0 network) copy it and paste below and give 192.168.1.0
in the same file search for --- smart host--- here type the abc.com and copy the same line and paste it and give xyz.com...
now it will work for two domains.


i think it will work for you...

This is my sendmail.mc for 1 domain
If I have 2 domain :
(1) mail.abc.com
(2) mail.xyz.com

which part (sendmail.mc) should I edit ?
And I want masquerade it as abc.com (if mail.abc.com) and xyz.com(is mail.xyz.com).How to do it ?
Thank you.

Any idea ?

Since your .mc contains:
you can go to your sendmail.cf, find the line "Cwlocalhost" and after that there must be a line starting with Fw and the path to a filename (at my slackware the filename is local-host-names)
Edit that file and add the domains you want (one per line) and restart sendmail.
Of course you must a dns server configured for those domains with the MX records pointing to your email server.

Hi,

In my /etc/mail/local-host-names file contains :
mail
localhost
abc.com
xyz.com

What I have done :
1. I have masquerade as abc.com because I want a receipient will see it is from myname@abc.com not myname@mail.abc.com

The problems :
1. If I send email from domain xyz.com, a receipient will see it is from myname@abc.com not myname@xyz.com (I understand it happen because I have masquerade it as abc.com)

What I want :
1. If I send email from domain abc.com, a receipient will see it is from myname@abc.com
2. If I send email from domain xyz.com, a receipient will see it is from myname@xyz.com
How to achieve my goal ?

Any idea

"Any idea" why I say this?!

Again, a simple way to control Sendmail('s cf) for newbies and for admins is using webmin and the sendmail module.
