Hi, Jeremy -
We used to compile Exim from source, but current policy here now is to use
the version from the Ubuntu distribution: the LTS version, sadly, so I
don't get fixes for up to 2 years. (So it might be something I need to
discuss again with our Head of Group. :-)
I've just posted a follow-up message (which you've probably read by now)
with my analysis of why I think it's not getting logged. The TL;DR version
is:
1. Missing Message-ID value gets generated and header added to message
structure
2. …but isn't recorded in the msgid_header variable
3. …so the logging code later sees msgid_header is still NULL so doesn't
log anything for the message-id.
I'll send in a bug report detailing this and discuss returning to compiling
from source with colleagues.
Cheers,
Mike B-)
