We (the system administrators) have lost our battle against
disclaimers and have to implement it now.
I have tried the suggestion in the Exim Book (page 94) in combination
with the script Kjetil supplied:
========================
In the Transport section:
remote_smtp_filter:
driver = smtp
transport_filter = /usr/local/bin/disclaimer
And in the router section:
smarthost:
debug_print = "R: smarthost for $local_part@$domain"
driver = manualroute
domains = ! +local_domains
# transport = remote_smtp_smarthost
transport = ${if eq {$sender_address_domain}{sun.ac.za}\
{remote_smtp_filter}{remote_smtp}}
route_list = * DCsmarthost byname
host_find_failed = defer
same_domain_copy_routing = yes
no_more
=====================
But I get the following error:
T=remote_smtp_filter defer (-24): transport filter process failed
(127): unable to execute command
The script seems to work:
=======================================
$ a="Dit is nou 'n e-posboodskap"
$ echo $a | /usr/local/bin/disclaimer
MIME-Version: 1.0

Die byvoeging van hierdie item is 'n dom idee
---=-1537-burger.sun.ac.za-
=======================================
I don't understand enough of what is happening in the process when
exim calls in this script. Therefore I do not know how to debug it.
Is there a tutorial somewhere on what must happen in the communication
between exim and an outside command changing the message?
And how do I debug this? I have tried "exim4 -d -bh 1.2.3.4" but this
did not help me to see what goes wrong.
Regards
Johann
