Hi, i want to create an SPF record but:
- My hosting provider hasn't an SPF area, but only TXT area

- Surfing the web i can find a lot of info or best practices, but i don't know which follow ("don't use INCLUDEmechanism, if you use A mechanism you have to first create a dns A record, don't write more of 405 char, don't use ~ALL because it cause SOFT FAIL.....and so on)

- we send mail with two different SMTP Authenticad server, external to our network. Only in case of trouble, directly with our MX record

- trying to validate my txt spf record here:
http://www.kitterman.com/spf/validate.html
i receive Ok but with a warning a can't understand:
Results - record processed without error.
The result of the test (this should be the default result of your record) was, ambiguous . The explanation returned was, SPF Ambiguity Warning: No MX records found for mx mechanism: example.com


- this is record i created:
v=spf1 mx include:_smtpsvc.xxxxxxxxxx.com include:_spf.yyyyyyyyyyyy -all

Please help me creating a correct and validate record for my domain, and clear me benefits of making it.
Really thanks, sorry for my english, ask me for details
