Do I have to publish spf for each of my smtp servers?

No. You should publish spf records for each and every domain you wish to
protect from being used by spammers/virusses. If, for example, your domain
is somedomain.tld and you furthermore have a subdomain www.somedomain.tld
registered, you would publish for both somedomain.tld and www.subdomain.tld
(the latter probably being set to "v=spf1 -all"). Note that you will have to
publish for each and every A record, including any wildcard (*) or @ entries
in your dns.
