Yes, this indeed turned out to be the case. It is fixed by setting
sr->sr_nmatch to zero in smtp_reply_init().

I have uploaded a fix for v4.1.10:
http://files.eschauzier.org/milter-greylist/no_autowhite-4.1.10-2.patch

Besides the regex change, the file also includes a patch that rolls
all of the greylist and autowhite action into a single list,
effectively eliminating the autowhitelist. This mod is based on the
observation that a tuple entry can only exist in one of the pending
and autowhite lists at any given time.

Merging the lists into one, practically means that if a greylisted
tuple comes in for a second time, the tuple is found in the combined
list, after which the type of the entry only needs to change to
autowhite (instead of deleting the entry in the pending list, and
creating a new entry in the autowhite list).

Combining the two lists should give a good performance boost, since
milter-greylist only needs to traverse a single list, instead of two,
for each message that comes in.

Also, since all the files relating the the autowhite list have
disappeared, this is one of the rare occasions that the code actually
becomes smaller with time ;)
