As Mark says, they should use an @sysadmins.irs.gov address or
something like that, which would have its own p=none policy.  Note
that this has been already standard practice at Yahoo! (!), AOL (!!),
LinkedIn, and several banks that participate in IETF discussions.
Since 2013 for Yahoo! and LinkedIn IIRC.

This need not be burdensome.  Many MUAs support automatic
"personality" switching based on addressee.
