i understand this but i read something on openspf.org about the HELO name so
in addition to the first entry
afnet.net. IN TXT "v=spf1 mx -all"
i need to add the 2 other lines,
next is a copy from the openspf.org site
If you run BIND
Paste this into your zone file:
afnet.net. IN TXT "v=spf1 mx -all"When a mail server sends a bounce message,
it uses a null MAIL FROM: <>, and a HELO address that's supposed to be its
own name. SPF will still operate, but in "degraded mode" by using the HELO
domain name instead. Because this wizard can't tell which name your mail
server uses in its HELO command, it lists all possible names, so there may
be multiple lines shown below. If you know which hostname your mail server
uses in its HELO command, you should pick out the appropriate entries and
ignore the rest.
So this should also appear in DNS. You may or may not be in charge of the
DNS for these entries; if you are, add them.
mail2.afnet.net. IN TXT "v=spf1 a -all"
mmail.afnet.net. IN TXT "v=spf1 a -all"
