The main argument against SPF is that there can be false positives when sending an email to an address which uses email forwarding, where the forwarding service doesn't rewrite the sender envelope, and where the service being forwarded to does strict SPF checks. This isn't as big a problem as it's made out to be. I've been using "-all" on my own personal mail for years now without noticing any problems. -- Mike Cardwell https://grepular.com/ https://twitter.com/mickeyc Professional http://cardwellit.com/ http://linkedin.com/in/mikecardwell PGP.mit.edu 0018461F/35BC AF1D 3AA2 1F84 3DC3 B0CF 70A5 F512 0018 461F
