Does Exchange support plussed users (e.g. myname+spam@example.com) or a similar mechanism?

Question

Sendmail supports a feature called 'plussed users'. Once enabled, emails sent to

• myname+spam@example.com,
• myname+sometopic@example.com and
• myname+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.

Answer 1

No, Exchange doesn't support this. A similar feature (nicknamed "disposable e-mail addresses") was proposed for Exchange 2010, but it didn't make the cut.

Answer 2

I'm not saying definitively, but sending to my username "+test@" work (E2k3) email did not come through. I'm not willing yet to say that it doesn't work at all, but it doesn't work in my environment.

Also a cursory search of the web does not come up with any references. It may be possible to enable this behavior, but I don't know how.
