Yes, this is no different from any other alias or virtual setup that 
offers multiple addresses to individual users. You would handle this in 
the MTA. For example, I use virtual_alias_maps with Postfix, and map all 
addresses to the corresponding cyrus IMAP user:

  abuse at example.com		admin
  admin at example.com		admin
  postmaster at example.com		admin
  bob at example.com		bob
  robert.smith at example.com	bob

You can also use the aliases file and other approaches.
