Hello.
According to section 3.4 of Exim 4 Specification [1], there
are 4 methods a locally running process can use to issue
a message to Exim:
1) -bm option
2) -bS option
3) -bs option
4) TCP call to loopback address
I would like to route those locally generated messages in a
specific way.
QUESTION:
How can one to reliably detect a locally generated
message (issued by a locally running process)? Is
it possible to write a router which handles only
messages received through one of those 4 methods?
Or, at least, through the first 3 three (which
don't involve TCP/IP) ?
Any hints greatly appreciated.
Many thanks,
Everton
