Milter-greylist

Hello,

I'm using milter-greylist with SPF-Support and have the problem that
the SPF Return Code changes sometimes to another value:

The first mail gets

milter-greylist: SPF return code 3

which is correct because I wanted to produce a "fail".

All the following (identical) mails, sent a minute later get:

milter-greylist: SPF return code 6

Which is SPF_UNKNOWN AFAIK.

This seems to be an error, or am I missing something?

Regards,

Sebastian
