Hello all!

I have a small problem, could gimme a hand in this or point to where i can find some info?

I have 4 servers running rhel as3.0 in a network.
my need is simple: i need to to be able to send email from one server to another. among all four.
how to achieve this?
Right now using the mail command from server A as:
"mail me@serverA.domain.com" i get the mail on my own serverA.

But i need to be able to use:
"mail someoneelse@serverB.domain.com" and it should be received at B.
Currently it is not and is bouncing to the root user on the same machine.

The /etc/hosts looks like this:
10.3.1.222 serverA serverA.domain.com
10.3.1.223 serverA serverB.domain.com
10.3.1.224 serverA serverC.domain.com
10.3.1.225 serverA serverD.domain.com

in the sendmail.mc/cf file, the line exhorting "accepting connections...127.0.0.1.." has been commented and sendmail restarted on all machines.
I noticed that domainname is not actually set for any for any servers, i.e.
hostname gives serverA.domainname.com
but domainname gives blank output.

could anyone please guide me how???

thanks in advance.

Hiya,

Seeing as this is an internal mail process, I'd suggest you paste the accurate information in your post because <someone@somedomain.com> such information is a bit tedious to work through.

Cheers,

hiya mtimbro,

sorry, i know it sounds stupid, but i thought i was simplifying.

the actuals are this:
/etc/hosts looks like this:

10.3.1.250 controlserv controlserv.afb.com
10.3.1.253 commserv commserv.afb.com
10.3.1.251 matserv1 matserv1.afb.com
10.3.1.252 matserv2 matserv2.afb.com


As i mentioned earlier, from controlserv i need to send email to commserv. Or to any of the other machines as in using:
mail mark@commserv.afb.com
or mark@matserv1.afb.com.

But currently, the mail is not getting delivered at commserv or others using this.
I am sure the line pertaining to..127.0.0.1...is definitely commented with a dnl suffix and restarted.

thanks in advance

and yes, mark is a valid user on all servers.

You should probably uncomment the 127.0.0.1 listener since it doesn't hurt and usually helps except in specialized situations.

RHEL is distributed with mail disabled so a new installation does not open common ports unless you configure them. This is done by leaving out definitions for any non-localhost listeners in sendmail.mc. On each of your systems add a line to define a listener on your 10 network, for example on commserv add:
Try "dnsdomainname". The "domainname" command is for NIS/YP, so blank output is correct if you're not using NIS.

you could use /etc/aliases to have roots mail delivered elsewhere
have it look like this
root: myname@mydomain.com

and run the command "newaliases" afterwards
