Has anyone recently encountered any “modern” mail system that can’t handle SPF macros? The RFC is about a decade old at this point.
I don’t care if Exchange 2003 can’t handle them, but does anyone know any reasonably modern system that doesn’t? I know all our systems like them just fine, and I’m sure “the big MSPs” will, but we do exchange email with some companies that might have older mail systems. I’m especially interested in hearing from anyone who tried to roll out SPF macros, and had to roll-back after encountering any issues with other sites with whom they were trying to exchange mail. Regards, Tom
