The SPF record should contain A and AAAA of Mozilla.cz (from webserver WordPress sends info e-mails for us and phpBB on forum.mozilla.cz sends notification for answered support questions and registration confirmations) + the mail servers. "v=spf1 a mx include:spf.cesky-hosting.cz ~all" Feel free to change the policy to "?all", if it's preferred for Mozilla domain, but I hope "~all" is better.

TXT SPF record added for Mozilla.cz. Should be visible as soon as it transfers out to the main nameservers.
Already visible for me and the e-mails pass SPF test.
