Email authentication

Excuse if this is the ?wrong forum? but I have been having a few emails go to junk folders at various addresses and I have discovered I do not have SPF (or DKIM) set on the server. I read that SOME inbound mail systems 'object' to this so - should I set them?

Yes, I believe more and more mail systems are requiring these to be set so I think you should set them.

Thanks. Will do.
