DNS support for SRV & SPF text records?
A client of mine is requesting additional DNS records beyond MX IP specs and priority for remotely hosted mail servers. One is SRV (Service Locator Records) http://support.microsoft.com/kb/940881 ; the other is SPF (Sender Policy Framework) record. In tandem, these are designed to be a DNS level spam filter, though I've always thought smtp spam filters and RBL lists are sufficient to block spam. Microsoft hints some DNS server aps (I suppose Apple's) may not support SRV and/or SPF entries in hosted domain tables. Anyone here know for certain one way or another. And if permitted, what can I do in Terminal to bypass the GUI?
