Are there any domains with CSV records now available? I'm writing a Python
script to check authentications, and I would like to include CSV.
I recently posted the following comment to a circle-ID article:
For what it is worth, earlier this week I did a survey of 135k domains
used in the SMTP HELO command. I found over 3750 domains with SPF
records at the HELO level, while I found only 24 CSV records. (The
number of records is more than the number of domain owners because
there are often several MTA hostnames per main domain name. For
example, the 24 CSV records were published by just 5 domain
owners. There were probably only 2500-3000 domain owners publishing
SPF records, although some of those domains send a huge amount of
email.)
I think HELO checking is useful. If you like HELO checking, I highly
recommend publish SPF records at your HELO domain level. Systems such
as spamassassin have been checking the HELO domain for SPF records for
at least a year now. If you want to do HELO checking, I highly
recommend checking for the SPF records. They are far more widely
published than CSV or DMP records.
The HELO domains that I found with CSV records were:
