+JH/32 DKIM: when a message has multiple signatures matching an identity given
+ in dkim_verify_signers, run the dkim acl once for each. Previously only
+ one run was done. Bug 2189.
+
+JH/33 Downgrade an unfound-list name (usually a typo in the config file) from
+ "panic the current process" to "deliberately defer". The panic log is
+ still written with the problem list name; the mail and reject logs now
+ get a temp-reject line for the message that was being handled, saying
+ something like "domains check lookup or other defer". The SMTP 451
+ message is still "Temporary local problem".
