I am new to DNS and SPF but I think I almost understand it. Could you
tell me whether I have this right? I'll use cryptic aliases to make it
easier (I hope).
1. I have 3 domain (A.com, B.com, C.com) hosted at HOST.com. So all
have the same IP, HH. HOST.com has its DNS server.
2. B & C are subdomains of A, (i.e., B.com => A.com/bb and C.com =>
A.com/cc)
3. HOST.com got blacklisted by yahoo.com. That's been fixed. They had
no PTR or SPF records in DNS, only A, CNAME and MX I had to learn this
stuff and tell them what they had to learn and do to keep it clean.
4. HOST.com also has a mail quota too low for my mailing list.
5. So I
1) got domain MAIL.net FROM GoDaddy,
2) switched to ISP.com to get static IP MM.
3) set MAIL.net to point to MM
3) got an SMTP server to run on my WinXP system (ughh).
6. I want to send mail *for* A.com, B.com, C.com *from* H.com and
M.net. Are these SPF records right?
A.com IN TXT "v=spf1 ip4:MM ip4:HH -all"
B.com IN TXT "v=spf1 ip4:MM ip4:HH -all"
C.com IN TXT "v=spf1 ip4:MM ip4:HH -all"
7. This goes in both GoDaddy's DNS (for MAIL.net) and HOST.com's DNS
(for A.com, B.com, C.com), right?
8. I must put a PTR record in ISP.com's DNS (for MAIL.net) and
HOST.com's DNS (for A.com, B.com, C.com), right?
Thank you.
