Right....
Anyways. I am using a envelope-sender-signature just for two purposes:
1. If a mail from <> reaches my MTA without a "valid" envelope-to (that
is a signed address) it is bounced.
2. same goes for mails from postmaster@*.
All other mails are not subject to signature verification. Since mails
from <> are - at least to my understanding - only supposed to be last
resort mails like NDRs etc. and since - again from my understanding and
practical experience with this method - these messages (and sender
callouts) seem to use the envelope-from, I fail to see why this method
poses any big problems.
Please do not answer by citing 1 trillion RFCs. I am interested in why
this will produce REAL problems and not why it might not be in 100%
conformance with a RFC.
