hotmail send bare LF

Hi,

it seems, that hotmail send a bare LF in the added signature
(and violates RFC).

qmail drops the connection afterwards:
451 See http://pobox.com/~djb/docs/smtplf.html

no helpfull response from hotmail:

Kind regards,

Obviously not as good a solution as having Hotmail fix their issue, but the
fixcrio application (http://cr.yp.to/ucspi-tcp/fixcrio.html) is designed to
correct this particular issue.

I have always thought it funny that DJB has a stance of "strict compliance
sending, loose acceptance receive" in his MTA except for this one particular
issue.

Anyways, good luck.
