Sendmail supports a feature called 'plussed users'. Once enabled, emails sent to
myname+spam@example.com
,myname+sometopic@example.com
andmyname+anything@example.com
are automatically delivered just like mails to myname@example.com
. There is no need to register or set up these 'plus suffixes'. The user can just use them and set up client-side filtering rules on his own.
Does Exchange support a similar mechanism? If so, how to enable it?
Note that I don't want answers about other means of filtering, e.g. spam/junk filtering, server-side or client-side rules, email aliases/addresses that are configured explicitly and so on.
