I have 2 domains and both domains send and recieve for each other.
i have used the following tool to create an spf record for zzzplace.com
and used http://www.zzzman.com
to test my spf record
if I send from firstname.lastname@example.org it works fine as it should, but if i use email@example.com it comes up with the follwoing error
Mail sent from: 78.33.xxx.xxx
Mail from (Sender): firstname.lastname@example.org
Mail checked using this SPF policy: v=spf1 mx mx:exchange.stanleyzzz.co.
uk mx:argonaut.zzzplace.com ~all
Results - ambiguous SPF Ambiguity Warning: No A records found for: argonaut.zzzplace.com.stan
any ideas as some of our users have mailboxes on the above server and need their primary smtp address as above and it does send ok to come servers/clients but some we are getting blocked either by "possible forged sender" or "failed to meet SPF requirements" even tho reverse dns is setup ok and i have also checked with dnstuff.com
i have also setup mx records for both and A records
