I have just installed red hat linux v5.  It is a internet server for www,ftp and email.  Sendmail is working fine, in and out, from the server box.  But the clients (Win95, or WinNT) are having trouble sending mail to the outside.  I am using Microsoft Internet Mail program, and it returns a message 551 <XXXXXXXX>  "we dont relay".  I am not at the office and i cant remember the exact message.  The <XXXXXXXX> are something else i cant remember either.  But the message "we dont relay" or something like that hinted to another coworker that the problem may lie in the /etc/mail/relay_allow file on the linux server.  Neither of us know what the syntax is for this file and i could not find any documentation.
Are we headed in the right direction?
Do you know the Syntax of the /etc/mail/relay_allow file?
Thanks

I am not sure i understand your answer.  Is this a list of each client in our LAN?  If so, then i guess this is how everyone in our LAN could have and receive email, but only certain workstations to send email to the outside!!   Is this correct?

I have now tried to enter the clients name in the /etc/mail/relay_allow, and i still get the same error.

551 < email@address.net> ... we do not relay

I have tried each of the following at seperate times:
1. the hostname of the client
2. the hostname.domain.com of the client
3. the IP address of the client

After each time i stopped and started the sendmail daemon.
Should this have worked?
Do i need to stop and restart sendmail when changes are made to /etc/mail/relay_allow?
Where would i find documentation on /etc/mail/relay_allow?

Thanks

I am sorry I did not read documentation carefully...
You should add all ip addresses to
/etc/mail/ip_allow

Here is a part of sendmail.cf
----------------
# file containing IP numbers of machines which can use our relay
F{LocalIP} /etc/mail/ip_allow
----------------
