Comment 2 for bug 1624394

I can confirm Richard's patch. I rebuilt a package and since then reread works very well. A good idea might be to place a script in /etc/mail/spamassassin/sa-update-hooks.d to automatically reread mimedefang after sa-update. I guess most users forget a reread after sa-update therefore new updates never catch until reboot or manual mimedefang restart.
