Since hotmail.com has got a *large* spf range , will it make my
spamchecks any slower ??
Hotmail SPF consists entirely of ip4 mechanisms (glued together with
include). It is one of the faster records to evaluate.
What makes SPF slower is lots of DNS lookups, like MX mechanisms.
Further, as long as you're running a caching name server in front of
your SpamAssassin installation (like you really should be), you'll only
incur the lookups once an hour (Hotmail's SPF record's TTL). Any
messages that go through in the same hour will basically get an SPF
check for free.
