SPF/TXT records

[David Ford]

There is no perfect solution which either a) is technically correct for 
everyone, or b) is religiously correct for everyone.

Rather, try to learn how to best implement a given solution correctly 
such as SPF if it has value to your organization.  There will always be 
someone foaming at the mouth to oppose any position you take regardless 
of whether a solution is good, or bad, for you or anyone else.

People foam at the mouth against BIND.  Against sendmail, against emails 
that aren't plain text and hard wrapped at 72 columns, and any other 
editor than vi.  Leave them to their religion, there's no point in 
debating something with someone that won't consider a possible benefit.
