Everyone has different opinions on the usefulness of SPF, but the reality of it is, DomainKeys solves the entire problem. SPF doesn't.
I second that. I've wasted a lot of time with SPF and it's useless.
Maybe. Or maybe, more exactly, is useless to use, but it's necessary to have. The reality today is that if you manage a mail server you simply have to get your SPF right, no matter what you do or do not with SPF of _incoming_ messages. What the message that starts the thread means is that, if anybody with a @dovecot.org address (or any other domain address with the same SPF status) sends a CV to some dream company he'd like to work for, but the address he wrote is an hotmail one (or is forwarded to an hotmail one) that company will never see his CV and hire somebody else.
And there are too many people with an Hotmail account (and you not knowing they have an hotmail account) which you or your users may NEED to contact to ignore such cases.
