It is interesting that Google's Gmail allows a name+suffix.
Filters allow binning of the messages.

In addition dots are ignored.   bob.johnson is the same as b.objohnson

Other mail tools can collect the message and validate a signature per a
local method.

I have used it to flag messages as important from friends with a pre-shared
magic word.

    friendly.guy+magickey at gmail.com

Most of the interesting filters are tedious on pure Gmail but other "pop"
or "imap" clients are easy.

Attachments are the obvious payload even compressed clear text or MS
documents.
Tar balls can be renamed with a checksum that can be shared in other ways
to limit
tampering.
