just because customers want their newsletter doesn't mean you can send
"bad" mail. The problem is that you need to think of exceptinal cases:
- what if the address does not exist anymore?
In "normal" MLs, user gets unsubscribed after some number/duration of
bounces. and this is generally automated.
- what if the subscriber has left the company, and the address cannot be
removed because it receives important mail?
In "normal" MLs, it is easy to send an unsubscribe request using the
user's address. some lists include infos on how to unsubscribe. others
obey a standard model (-unsubscribe, ...etc).
The problems really happen when
- the mktg dept ask a developer to setup a newsletter UI on their
webserver or whatever.
- email is relayed by the local MTA, where abuse and postmaster are
handled by sysadmin, who has no idea how the newsletter is managed
- worst: lists of users are shared as excel sheets. go get them updated!
... etc.
noreply is a valid address. The problem is not with this. If the
messages contain information that will easily guide you to get an
address unsubscribed, then it's ok. otherwise, we want a channel to get
in touch with someone. I mean a human. a web page that shows "php error
in ./inc/.... blah blah" or "sql error in ..." just drive me mad. I too
can setup a spam site, claim that you can unsubscribe and create a
program to issue fake errors !
