Configure Sendmail to Forward mail to a mail server

[naqi]

Hi,

How would i go about configuring sendmail to forward mail to another mail server which runs on the same host?
What happens is, an application sends email using the sendmail command(/usr/lib/sendmail or /usr/sbin/sendmail), this mail then needs to be forwarded to a mailserver that is running on the same host - it is then this mail server which deals with the mail transport. What sort of entries do i need to make to the sendmail.cf file to accomplish this.
Any help would be appreciated

That is precisely what the sendmail command does. It connects to localhost:25 and sends the mail via the MTA listening to it.

Yeah thats what i thoguht aswell. See i have oracle;s email server running, and on using the sendmail command, it does show that it connects to the oracle email server, however no mail is ever recieved?, i get a message 'mail loops back to me'.

According to the oracle documentation, i am supposed to do the following:

Perform the following steps:
1. Open the sendmail.cf file as root and locate the line that contains DH.
<this was easy......done>

2. Add the middle tier host name to the end of the line, as follows:
DHmiddletier_host
<done>

3. Comment out the following lines in the # short circuit local
delivery so forwarded email works section:
R$=L < @ $=w . > $#local $: @ $1 special local names
R$+ < @ $=w . > $#local $: $1 regular local name

<done these lines now look like the following in my sendmail.cf
#R$=L < @ $=w . > $#local $: @ $1 special local names
#R$+ < @ $=w . > $#local $: $1 regular local name
>

4.Note: This step is only necessary if your Oracle Calendar and
Oracle Email servers are installed on the same computer.

Add a k to the end of the F= parameter string of the mail deamon being used in
the sendmail.cf file. To determine the mail deamon being used, enter the
following command:
/usr/lib/sendmail -bt
3,0 OCS_test_e-mail_address
The parameter string to which you add the k looks like F=mDFMuX.

<to be honest this was confusing - my lack of knowledge on sendmail, so for this i scanned sendmail.cf and found only one like that had :
F=mDFMuX

I then changed it to

F=mDFMuXk

However the mail is never recieved or delivered. Any ideas what i should look into, or perhaps i have not followed those steps correctly?
Thanks

Scan the loopback interface with ethereal or tcpdump and see what happens.

yup the problem is now resolved, I was supposed to put the 'k' in the line for estmp as this was the mail daemon being used by sendmail, i thought it was smtp, now everything works fine.
