[exim-dev] Bugzilla maintenance (security upgrade); old mail…

Bugzilla had a security release today; I have upgraded bugs.exim.org to
4.4.13.

Part of the pre-flight checklist involved running a sanity check, which
found two bugs with unsent mail. I sent those mails out. This sent out
messages dated 2017-03-07 for bugs 1294 and 1998.

Sorry; if I'd known they were so old, I'd have nuked them instead (if I
could figure out a sane and safe way to do so).

We're all back and running fine now.
