Arriba Arriba Andale Andale!

P.S.: i also have written a graylister for postfix, in C.
94003 bytes, works just smooth for months; is a package in Alpine,
and has a focus-sender mode that i now use and that is in no way
worse than long delays.  In fact better to me, because i also have
private correspondance from the server, and many german companies
and such use pressing service providers which hammer you from (the
original and) multiple (other) IPs if the first mail is delayed.

	delay-min=0

	focus-sender
	# ! --focus-sender
	  #count=2
	count=1
	msg-allow=permit
	msg-block=REJECT
	msg-defer=DEFER 4.2.0 Service temporarily faded to Gray

	allow .alpinelinux.org
	allow .osuosl.org
	allow sdaoden.eu

Just in case; i drive it with 0.00 CPU time per week in less than
a megabyte of RAM; it could make the box less busy.
