So, for my Ringlink system which is sending mail from my domain, how
would I add SPF records for that domain, and know which mail
server/s to use/allow?
An initial guess would be that it's sufficient to have this SPF record
in the zone for webring.cc:
v=spf1 a a:webringworld.org -all
The first 'a' would allow for sending from Ringlink, forms, etc.
installed on the web host for webring.cc. 'a:webringworld.org' would do
the same if you are using @webring.cc addresses at webringworld.org.
When you get a decent ISP, that allows you to use whichever sender
address you like when sending from their server, something reflecting
that would need to be added.
Not to mention the bounces going to member Ringmasters, how would
they be handled?
That's the problem I mentioned in the initial post in this thread.
However, assuming that those ringmasters are using other addresses but
@webring.cc, an SPF record for webring.cc won't make a difference.
Maybe just a ?all 'neutral' like AOl for now,
Yeah, that's an option if you are not sure that everything is covered.
but then why bother??
Actually, if I have understood this correctly, having an SPF record
might still make a difference. For instance, some receiving mail servers
appear to use the information to determine which filters to apply, and
some believe that an SPF record reduces the risk that legitimate
messages are caught in various spam filters.
