Hi,
I am somewhat confused, even after rereading various parts of the
documentation, about how I can manipulate messages in the system
filter. I would like to add or drop recipient addresses from a
Embedded Perl subroutine that gets called from the system filter, but
I am not sure how I can do that:
spec.txt tells me that the command-line options
-Mar <message id> <address> <address> ...
-Mmd <message id> <address> <address> ...
-Mmad <message id> <message id> ...
(and some others) do not work while a message is active (in the middle
of a delivery attempt).
Then...
,----
| 47.1 The system message filter
|
| The system message filter operates in a similar manner to users' filter files,
| but it is run just once per message (however many recipients is has) at the
| start of a delivery attempt, before any routing or directing is done. If a
| message fails to be completely delivered at the first attempt, the filter is
| run again at the start of every retry.
`----
Is the message considered "active" when a system filter is run? Would
a call to exim -Mmd from my Perl subroutine be successful?
If not, how should I read the following lines?
,----
| 3.5 Delivery in detail
|
| When a message is to be delivered, the sequence of events is roughly as
| follows:
|
| . If a system-wide filter file is specified, the message is passed to it.
| The filter may add recipients to the message, replace the recipients,
| discard the message, cause a new message to be generated, or cause the
| message delivery to fail.

Thanks for enlightening me.
