No, because you are replacing a service that operates on a "push" principle - which is the very basis of email - by a service that operates on a "pull" principle. You don't need any active action on your part to receive email someone sends you, even if it is forwarded. On the contrary, you *do* require constant active checking of the POP account you want to download mail from. If you stop checking, you won't get the mail. If you change the password on your POP account, you need to change it also on the downloading side etc. - a lot of actual inconveniences. With that way of thinking, you can get rid of email completely, and just regularly check some website where people can write messages for you... And, taking into account that POP is quite outdated, many sites don't implement it anymore and offer IMAP only. So downloading via POP won't work anyway. > If forwarding mail is so important, can a better system > for handling forwarded mail be developed? Since forwarding was before SPF, I would trun this question the other way: if checking the "legitimacy" of the sending server is so important, can a better system for handling this (that takes mail forwarding into account) be developed? Myself, I don't think that SPF and other methods of checking "authenticity" of the email are so important at all. Normal, unsigned email is an *untrusted* method of communication *by definition*. If you want email to be "authenticated", you should end-to-end sign it with your PGP or PKI private key when sending. Period. I don't check SPF, DKIM or DMARC on incoming mail at all. Content checking and blacklist checking is much more important in actual spam prevention than doubtful "authenticity" checking. That's of course my opinion, you can have a different one. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
