####My Querry 
 Hi,

I have some peculiar problem with sendmail, can u
help me in fixing it up. I have attached one ppt file
along with this mail for ur reference.

All the Servers are on Red Hat Linux 7.0 .As u can see in layout.ppt 
gmail and dmail are in in.abc.com domain, and Tgate.abc.com is the Mail gateway 
server. 

I am modifying default sendmail.cf file , now when i give following 
command on gmail.in.abc.com it gives

#1 sendmail -bv girish it says deliverable local
and if 
#2 sendmail -bv ragesh it says deliverable host dmail.

So far its OK..

But as soon as i put Smart relay host as Tgate.abc.com, 
the result for sendmail -bv ragesh
is deliverable  mailer relay, host Tgate


Can u pl. suggest what could be wrong, my DNS is up and running ...
I have checked the DNS its perfectly  ok. I have put in.abc.com 
entry in /etc/mail/local-host-names..


Pl. suggest as i am stuck up with this config.


Regards

Girish

Normally, it's not a good idea to modify sendmail.cf - use the mc file
instead.

 OK so far

 So what the heck do you expect when you tell qmail.in.abc.com to 
smarthost

 through tgate?  All non-local mails will be delivered only to your

 smarthost, for onward delivery.  DNS or no DNS ... in fact, you can 

just use
 a service.switch file to turn off DNS lookups if you are passing mail 

to a
 smarthost for delivery.

 Thing is, if you are absolutely insistent that the mail should go 

directly
 to dmail (despite the smarthost to Tgate) set up a mailertable

 in.abc.com     esmtp:dmail.in.abc.com (or esmtp:[ip.of.dmail.box])
 
 and makemap it.  I guess redhat's default sendmail config already has 
the
 mailertable feature included.

 [or if you only want dmail mail to go that way, put dmail.in.abc.com 
in the
 LHS of that mailertable entry above]

 You have accomplished precisely what you set out to accomplish.  You 
wanted
 one machine to handoff all non-local mails to another machine for 
delivery -
 you did that.

> I have put in.abc.com entry in /etc/mail/local-host-names..


 OK, so your box (whatever) treats in.abc.com as local.  Not very 
relevant in

 this case, given that you have /etc/aliases entries pointing to other
 machines in your LAN.

 
 If you'll take my suggestion, just set up NAT so that this linux box 

has
 full access to the 'net (outbound only) - and can send any mails 

destined
 for the 'net directly to the 'net, without a smarthost of any sort.  

Saves a
 lot of pain :)
