Hello,
This is basically
http://bugs.debian.org/208782 reported by Kevin
"Starfox" Arima <admin at furball.org> it talks specifically about
exiscan but applies to vanilla exim, too, e.g. this silly example[1]
warn log_message = Big message received: $message_size
condition = ${if >{$message_size}{6M}{yes}{no}}
will not only log the respective line in main.log but will also dump
the full message-headers to reject.log, which was not necessarily
intended, having log_info or similar that does not trigger dumping the
headers to reject.log woul be nice.
Just for reference: I did not search _very_ long but I failed to come
up with documentation for the fact that "warn log_message" writes to
reject.log at all.[2]
Please keep the cc on 208782-forwarded@??? on followups.
Here's the original report:
|-------------------------------
| Package: exim4-daemon-heavy
| Version: 4.22-3
| Severity: wishlist
|
| Because of the way most of exiscan's "features" works during the DATA
| phase, you cannot easily add log_message to log informative information in
| the exim logs without incurring an exponential increase in rejectlog.
| Because log_message writes to both LOG_MAIN and LOG_REJECT, and log.c adds
| the entire header of the message whenever anything is written to
| LOG_REJECT during the DATA phase, you cannot do simple things like:
|
| warn log_message = SpamAssassin score is $spam_score
|
| There should be a logging option (log_info) that only writes to LOG_MAIN
| so sysadmins can decide whether or not logging of the header is important.

[1] I am sure people can come up with more intelligent examples like
using delay to teergrube messages with unverifyable headers.
[2] On a sidenote: warn log_message... without any any other conditions
seems to be ignored, ie:
warn log_message = size $message_size
does not work but
warn log_message = size $message_size
condition = true
does.
