Change log file for Exim from version 4.21
-------------------------------------------
of host_find_byname() use the default settings of RES_DEFNAMES
(qualify_single) but not RES_DNSRCH (search_parents).
+PH/17 Applied (a modified version of) Nico Erfurth's patch to make
+ spool_read_header() do less string testing, by means of a preliminary
+ switch on the second character of optional "-foo" lines. (This is
+ overdue, caused by the large number of possibilities that now exist.
+ Originally there were few.) While I was there, I also converted the
+ str(n)cmp tests so they don't re-test the leading "-" and the first
+ character, in the hope this might squeeze out yet more improvement.
+
+PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
+ flag allowing group syntax was set by the header_syntax check but not
+ turned off, possible causing trouble later; (2) The flag was not being
+ set at all for the header_verify test, causing "group"-style headers to
+ be rejected. I have now set it in this case, and also caused header_
+ verify to ignore an empty address taken from a group. While doing this, I
+ came across some other cases where the code for allowing group syntax
+ while scanning a header line wasn't quite right (mostly, not resetting
+ the flag correctly in the right place). These bugs could have caused
+ trouble for malformed header lines. I hope it is now all correct.
