I thought PRT record is the same? or do i misundertand. Can you please explain the difference? and what must i do in my case? In my case several people do not get any mail, because there spamfilter blocks mail from our domains on our servers, due to Reverse or SPF settings . This is all i can understand, form the error messages. In my Power admin is no such thing as a SPF TYPE. only PRT / TXT etc.. I hope it is clear enough for you guys? Please let me know. thanks, Richard. Richard Vernooij wrote: I seem to have a problem that many messages from a webserver, or emailserver do not arrive on certain places.

Can you please explain the difference? and what must i do in my case? I am going to assume you mean PTR record. PTR's really only occur in .in-addr.arpa zones. They are for reverse DNS which is not SPF. Many sites do require *VALID* reverse DNS nowadays though, which is very different from SPF (which I'll get to in a moment). A *VALID* rDNS consists of a PTR in your providers .in-addr.arpa zone, as well as a matching A record that it points to (PTR means PoinTeR). SPF is simply a specially formatted TXT record associated with the sending domain which states which A, MX, or IP's can send mail on behalf of that domain. If you've got people denying mail because of no SPF record well you don't want to send mail to them anyway. SPF is seriously broken in the face of *many* everyday applications, including mailing lists, and remote dialup users. Now if you *have* an SPF record (which again is *NOT* a type of DNS record at all, it's a TXT record) and that SPF record is *wrong* I can see some net.kook's denying mail based on that. In my case several people do not get any mail, because there spamfilter blocks mail from our domains on our servers, due to Reverse or SPF settings .

If you've got people denying mail because of no SPF record well you don't want to send mail to them anyway. SPF is seriously broken in the face of *many* everyday applications, including mailing lists, and remote dialup users. I don't want to make this into a discussion about the merits of SPF, however, what you say isn't true. SPF has no problems whatsoever with 95% of all mailing lists. The problem that SPF has is with alias-style forwarding (where the forwarder simply forwards the mail with the MAIL FROM identity unchanged). Almost all mailing lists do rewrite the MAIL FROM when distributing messages, so there isn't any problem. About remote dial-up users, I assume you are complaining that they can no longer use SPF-protected domains for sending mail directly from their dial-up connections. All I can say to that is, well, that this is exactly the point of SPF. SPF gives owner controls over who can use their domains in e-mail. Complain to them, not to SPF. Don't shoot the messenger. To learn more about SPF and correct their misconceptions, I recommend that people actually read the SPF website[1] instead of propagating myths. Now if you *have* an SPF record (which again is *NOT* a type of DNS record at all, it's a TXT record) and that SPF record is *wrong* I can see some net.kook's denying mail based on that. Right. Whatever.

The RR is brand new and isn't used that much yet. Eventually only the SPF resource record is going to be used. This will take time. Let's not discuss SPF here. If you want to know why it is the user's fault and not the SPF record's fault, let's meet on the spf-discuss mailing list.
