Hi Jeremy,
Thanks for getting back to me.
--Please don't tell me
--it hacks on Exim's spool file; this is not a public interface for Exim
--and you should not do that. A transport filter should operate
stdin=to-stdout
--as a stream processor.
I'm afraid to tell you, with all due trying my bestest to abide by the rules
and reading this notice https://github.com/Exim/exim/wiki/Q1601, this is just
what I'm doing. Since it's only my personal email server and testing on some
features but if there is any official mail server which requires some legal
notices and warning, please rest assured I'm going to address it all lawfully.
Yet, I couldn't access message body nor headers from bash script? and I had to
fetch it from spool files while I don't edit spool files at all but I found
calling echo with concatenated headers and body does the job, as transport
filter, takes this and replace it with existing one.
Ah, so you script is asking echo to print the whole of the spool files ?
That mean that the argument(s) to echo will be exceeding ARG_MAX.
If you can freeze a large message in the mail queue and then from the command
line
run
/usr/exim/modifyemail.sh message-id
(with the correct message-id, not those letters) I believe you will see the
same error.
I read the documentation, here
https://www.exim.org/exim-html-current/doc/html/spec_html/ch-generic_options_for_transports.html,
it claimed message body and headers it's present somewhere in the stdin but
couldn't figure out which argument? would it be passed to modifyemail bash
script and under which name?
The message header and body can be read from /dev/stdin, or in bash with
the 'read' command amongst other ways.
They are not available sseperately.
