Dear Sir or Madam, I have a question regarding RFC 7208. Is a domain name e.g. for an "a:" directive supposed to be a FQDN; more precisely: can a domain name contain a trailing dot? e.g.: should this be able to be handled by any software that implements spf: v=spf1 a:domain.com. ~all Postfix for example has no problems with an domain name with trailing dot but I have found a software "mdeamon" which cannot perform a dns lookup if the domain name is a FQDN (with trailing dot). I wrote the developers but they say, they think it's not a bug in their software because "all of the pages about SPF, don't talk about domains with trailing dot" and the RFC does not make it explicit if a FQDN is acceptable. I hope you can clarify. Kind regards, -- Tobias Perschon Bitconnect EDV/IT Dienstleistungen & Handel e.U. -- https://www.bitconnect.at tp@bitconnect.at<mailto:tp@bitconnect.at> +43 (0) 699 10 86 75 17 -- This e-mail may contain confidential and/or privileged information.
