No, it doesn't. The first version of Courier that supported SPF _checking_ was 0.47.0. However, that doesn't matter in this case, because it was another server, not yours, that performed an SPF check. Be aware that the concept of SPF is comprised of two parts: (1) publishing SPF DNS records for sender domains, and (2) receiver-side checking of messages against published SPF records. (Publishing SPF records happens in the domain name system, and has nothing to do with the website at http://spf.pobox.com.) > A client is having some trouble when using authenticated smtp.

The one thing I can read from your report is that the MX of joimail.com checked the message relayed through your server for SPF compliance, and then rejected the message, probably because the message's MAIL FROM (envelope sender) domain did not have an SPF record. It is highly unusual for receivers to _require_ sender domains to have an SPF record. In the long run, if/when SPF has become ubiquitous, this will be a useful practice, but at this time, you just can't expect all domains to have SPF records. So you should tell [EMAIL PROTECTED] not to reject messages on an SPF result of "NONE". But it would of course be wise for the sender's domain to publish an SPF record anyway. Unfortunately, one can't tell which domain that is without seeing the original message -- was it attached to the bounce? ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
