Help Sendmail Is Driving Me Nuts

captgoodnight · 09-14-2003, 12:16 AM

HELLO, fellow penguins. HELP ! Sendmail is driving me crazy (bet ya heard this b4

Here it is,

I have a simple network behind a firewall, all I desire in my networking e-mail is that one machine can send another machine mail. Simple, I need not touch the outside world as far as e-mail is concerned. Sendmail works great as far as one machine sending mail to itself. All machines work fine in this regard. But, emailing machine b from machine a is a no go.? I get this error

from machine b;
Sep 13 20:22:52 localhost sendmail[12150]: h8DKMpBv012150: localhostlaptop [192.168.0.1] did not issue MA
IL/EXPN/VRFY/ETRN during connection to MTA

from machine a I get it looped back to myself.

I know it has to be something simple, it just has to be. It seems like it always is.... So, here's my machine b sendmail.mc

machine a is mandrake 8.2
machine b is mandrake 9.1

the mail command I try to issue is,
sendmail -v captgoodnight@localedhost.localdomain < stuff

I have played with the local-host-names file
I have played with the aliases file
I can telnet into 25 on both machines

Well, please help. I have tried to solve this myself, I have read as much as I can handle. Thank you -bests cg

Using sendmail does not send mail to other machines, it sends mail to other mail servers. You would need mail servers running on all your other machines to do things that way....

You WANT mail to get sent to your linux sendmail machine, you then need to tell the email clients on all your other machines to look to the sendmail server for mail. You will need sendmail AND a mail retrieval system such as pop3.

Basically your mail server will be responsible for sendmail everyones email to itself, and then using something like qpopper, you will retrieve that mail and make it available to your client, such as outlook, or kmail.

You will need to create users on your sendmail machine for everyone who will be sending email on your network.... if you already have a password server on your network, you can point it there as well...
