If a mail gets delivered to address, which is sending it further ("forwarding it"), the envelope sender has to be changed, because it's not the original sender who sends the another mail. Forwarding without changing envelope address is already broken, it's just people don't care without SPF.

They're talking about auto-forwarding, not people resending a message they received. For instance, mail to [email protected] is automatically forwarded by the alum.mit.edu server to my ISP email address. Many people also have vanity domains with auto-forwarding enabled like this.
I'm afraid the same applies even in these cases. How can you differ between vanity forwarder and spam/phish with fake from address?
Rewrite the sender's address. You have more choices, SRS is one of them.
This would help in other ways too - at my former employer we've had to deal with broken forwardings, therefore undeliverable mail and undeliverable bounces. Rewriting sender and properly detecting undeliverable garbage helps there too.
Who should the sender be changed to? AFAIK, it has never been standard practice to rewrite the sender when simply forwarding to an alias, which is what this is.
Because they did not care. Long time ago even open relays were not an issue until people started abusing them. ...OK this is off-topic here. However this was already discussed and the conclusion was that the SPF record is NOT dead. We just need enough time to deal with these issues. -- Matus UHLAR - fantomas, [email protected] ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
