DNS: Creating external "e-mail aliases"
I am wondering whether the same is achieveable with e-mail.
So, is it possible to add DNS entries so that any e-mail send to a subdomain will delegate to the "e-mail server" of an external server, without needing my server to actually process the data?
If so it would be possible to create a service where people can register their own e-mail aliases.
Thanks in advance.

Yes. The example on the zytrax site does just that:
; zone fragment for sub-domain us.example.com
…
; sub-domain mail server
IN MX 10 mail.us.example.com.
If you haven't delegated the subdomain, then a simple MX entry for the subdomain should do what I think you are wanting.
