Not so. By doing nothing (ie NOT creating an SPF

specific problems). It's the smart aleck admins who do create SPF records
etc who cause the problems, in conjunction with recipients that think these
records are worth paying attention to. The irony is that SPF was invented
by the advertising industry to ensure that their so called 'legitimate'
bulk mail gets through; it does very little to stop actual spam and it
completely messes up mailing lists and people who use traditional SMTP mail
while travelling. Sorry, I shouldn't start on SPF, it just drives me
crazy. If you are a DNS admin, *please* don't fall for the SPF bullshit.
(For some reason Microsoft are totally enamored of it and twist their
clients' arms to enable it :-/ )
You are preaching to the choir. Some of the first implementers of SPFs
were outfits that the rest of us would call spammers. As for Micro$oft,
my employer trashed our Zimbra and PMDF servers and sent us over to
Office365 so now I spend my time babysitting Exchange in the cloud,
writing PowerShell scripts, and waiting a Micro$oft minute for things
to happen that used to be immediate.
And you are right, Micro$ofts loves SPFs but they do nothing at all to
expedite our mail through their servers.
And in honour of Micro$oft, SPFs, and my 21st century managers, I am
retiring in 29 days.
