Hello,
Today I received and email telling me I need SPF records. But with no
information. I sent an email back requesting headers but nothing came
back. This is worse than having no SPF. It really is spamming me. Below
is the email. I have SPF records that expect failures. What are they
talking about. One area, that I think SPF missed was CNAME. I have tons
of host/domain pairs with CNAME. I really dislike having to change every
CNAME into an A record.
SPF works fine with CNAMES. If their implementation can't follow the CNAME,
then it's broken (I coded part of the CNAME support in pyspf and I know other
libraries support it too).
I know pyspf supports it. I just do not understand where this came from.
The only thing I could find was that maybe a CNAME was being used. But a
dig did give me the apporiate TXT record which should have allowed them to
get an SPF fail.
I know, but today I have had about 30 emails telling me about lacking SPF
records. I really think there are broken libraries or something. I
finally went in and change 200 CNAMES to A records late yesterday.
People really need to provide headers rather than spamming. The email
really is a spam. No substance what's so ever. Broad general statements.
I have had SPF records from the very start. So this just really upsets
me. I use -all to fail any message not allowed by my record. I just
notice a coupld of emails claiming you can no use a ? before entries
before -all. Which according to RFC 4408 is reasonable. They must really
have a broken library, that does not follow the spec in any way shape or
form. I really do not know what they are talking about. Without headers
I am shooting in the dark at a problem I really should not have.
Thanks,
