[exim] Exilog and logging subject lines

Hello,

I'm running Exilog as I'm wanting to log to a SQL database. I've enabled
subject logging in the exim mainlog, but Exilog doesn't seem to log
subject lines. Has anyone added this feature to exilog?

Alternatively, are there other ways to log (delivery attempts,
deliveries, retries, rejects etc...) to a database?

Thanks!

Andrew.
