Sendmail and Relay problem

[Daniel Ubeda]

Hi,

I have in one HP9000 the sendmail configured to relay all internal mails to one server with exchange (DS[192.168.110.xxx]).
If I use this HP9000 to incoming mails from other servers the response is: "we do not relay"
I want to send mails from others servers and configure this sendmail to relay all mails to the exchange.
What is the line in the sendmail.cf to change ??

thanks

You have to configure your HP9000 to allow relaying from your other boxes.

Build an access.db file from your /etc/mail/access txt file (using makemap)

In your /etc/mail/access file, add all your servers like this:

server1 relay
server2 relay

etc....

Then run makemap and restart sendmail.

Also, on those other servers, set the DS macro to point to your HP9000...

Exchange as I understand it does not have an access file for defining what servers can relay and which can't.

I was told by my exchange admin that I can't relay mail off Exchange without compromising security.

I had to change my DS directive to relay off of our firewall, which has an smtp gateway and can define who can relay and who can not.

If inbound mail is directed at the HP-9000 server, it should be accepted, regardless of the access settings, because its not being asked to relay its being asked to acccept.

A good test diagnostic from a HP-UX server is:

sendmail -v -d8.99 -d38.99 someone@yourdomain.net
type some text

.


You'll get a good diagnostic trace.

To test the relay issue and be sure, perhaps you have a HP workstation or a Linux box.

Try this command there.


sendmail -v -d8 -d38 someone@yourdomain.net
type some text

.



If you explicitly authorize it, I will send a test email to you from a HP-9000 server and email or post the results.

If you wish this help, please post back and we can do email.

I need a post because I don't check that account during the day.

Steven - I think your Exchange admin is on crack :)

They need to setup the smtp transport on Exchange - then you will be able to relay to it. That what we did at our site - we have all our Unix servers relaying to Exchange.

What I gather from Daniel's question, is he has a bunch of Unix servers, 1 of which he wants to be the master relay for all of them, and that one in turn forwards all mail to their Exchange server.

Thanks, Geoff is in the correct way. I want to resume in one server the mail (relay) service to send to exchange.

I configure this like you say, and work OK.

Thank you very much.
