No.
$ host -t txt postfix.org
postfix.org has no TXT record
$ host -t txt yahoo.com
yahoo.com has no TXT record
$ host -t txt mail.com
mail.com has no TXT record
and so on.
hotmail "recommend" that you set SPF (even sender-id) but that doesn't
really guarantee that your mail won't disappear...
> How do I check whether it has a SPF record or not?
$ host -t txt ozses.net
ozses.net has no TXT record
so this domain does not have an SPF record.
$ host -t txt ietf.org
ietf.org descriptive text "v=spf1 ip4:64.170.98.0/26 ip4:64.170.98.64/28
ip4:64.170.98.80/28 ip4:64.170.98.96/29 ip4:208.66.40.224/27
ip6:2001:1890:1112:1::0/64 -all"
you can try gmail.com, hotmail.com, ... etc.
