Okay, ... I'm not going to get into the whole aliases debate again
(likely already did that at least once somewhere on this list, or
Yes, you certainly do cover some very legitimate points, namely:
o sending and forwarding via aliases & authorized sending IP issues
(e.g. SPF), and similar issues.
o exactly where aliases do/don't forward to can be more
difficult/restrictive/restricted in who can see/examine (and sometimes

But aliases also have noteworthy advantages. (I've mentioned at least
some of them before, no need to get horribly redundant with the same
