[JDEV] Email trasnport

[Kevin Smathers]

Hi Julian,

It is pretty easy to insert a new agent into the sendmail.cf file; you
have to add two or three lines.  One or two to define the new delivery 
agent, and one to let the mail system know when it should use that 
delivery agent.

For setting this up I recommend getting the Sendmail reference guide
from O'Reilly as there really isn't any good source of documentation
for how to write your own delivery rules other than that reference.

Here is an example from a change that I did to my local system to 
gateway email into JADE.

*** sendmail.cf	2001/11/08 22:59:32	1.1
--- sendmail.cf	2001/11/12 21:45:48
***************
*** 754,759 ****
--- 754,767 ----
  
  # short circuit local delivery so forwarded email works
  R$=L < @ $=w . >	$#local $: @ $1			special local names
+ #
+ # -- ICE
+ #
+ R$+ . agent / $* < @ $=w . >	$#mail2agent $@ $2 $: $1	agent delivery
+ R$+ . agent < @ $=w . >		$#mail2agent $@ localhost $: $1
+ #
+ # -- ICE
+ #
  R$+ < @ $=w . >		$#local $: $1			regular local name
  
  # not local -- try mailer table lookup
***************
*** 1461,1466 ****
--- 1469,1484 ----
  SAddDomain=50
  R$* < @ $* > $* 	$@ $1 < @ $2 > $3	already fully qualified
  R$+			$@ $1 < @ *LOCAL* >	add local qualification
+ 
+ #
+ # -- ICE
+ #
+ Mmail2agent,		P=/usr/share/coolagent/mail2agent, F=lsDFMA:/|@qPhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL,
+ 		T=DNS/RFC822/X-Unix,
+ 		A=mail2agent $u $h
+ #
+ # -- ICE
+ #
  
  Mlocal,		P=/usr/bin/procmail, F=lsDFMAw5:/|@qSPfhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL,
  		T=DNS/RFC822/X-Unix,
--- cut here ---

In this case I added a new rule so that 'username.agent at host' would
ultimately be delivered through the 'mail2agent' mail delivery agent.
In my case this is a shell script that forwards the e-mail to my 
agent subsystem.  

You can write rules to grab any part of the address and use it to
key on how the mail should be delivered though; just write the rules.

Cheers,
