I've got just one. Do RFC3464 right!
There is no longer any excuse for not using DSNs. If sites would use
them (and use them correctly) we wouldn't need VERPs, which kill
performance unnecessarily. And we wouldn't need probes to find bad
email addresses.
My two biggest pet peeves about DSN implementations:
1. Syntax errors - The number of ways that MTAs incorrectly implement
what is clearly specified in the standard is beyond me.
2. Not using original-recipient - Although the use of the
Original-Recipient information is optional, not using it when the
final and original do not match is a waste of bits. It's worse than
not using DSNs at all.
There is something bad to say about every major ISP on the issue of
RFC3464 compliance.
