[Mimedefang] [PATCH] Memleak bug in mimedefang found and fixed

[Kevin A. McGrail]

This is in RedHat Linux 7.3.  It's very odd.

For example, I just added a small 1-byte text change (I put a dash in a
header name) in a change_header call.

I forced a reread using md-mx-ctrl reread.

I then sent myself a message and it still has the old header name without
the dash.

I then stopped sendmail, stopped mimedefang, started mimedefang and started
sendmail and the dash is there.

It's like a reread isn't really reloading the subfilter.

KAM
