Milter-greylist

Hello,

I got some strange syslog messages like:

skipping greylist because (from=<sender@...>, rcpt=(nil),
addr=...

After a short investigation I found
that in some case the whystr string variable
does not get a valid string assignment
and left with the original empty string value.

Please see the attached patch which removes this bug.

Bests,
Attila
