Milter-greylist

The current beta version of milter-greylist adds a @ character at the 
end of the email address when it logs authenticated users.

Also, there is not a Mail ID (?) for this entry, like other entries:
Aug 31 15:29:01 host milter-greylist: l7VKT13Q014778: ....

Here is the entry for authenticated users:

Aug 31 15:20:06 host milter-greylist: User user-name@...@ 
authenticated, bypassing greylisting

Thanks.
