You can avoid recursion by using RHS values in the expansions of
envelope recipient addresses that don't match any keys in the virtual
alias table!
Suppose each user (and the office mailbox) has two addresses:
- Public primary: user@acme.example
- Internal route: u...@mailstore.acme.example
Mail to either address is delivered to the user, though your MTA could
easily reject attempts to send mail to internal addresses from outside.
Then your virtual aliases become
office@acme.example us...@mailstore.acme.example,
us...@mailstore.acme.example,
...
... also archive copies, ...
The same approach applies everywhere else you don't want recursion.
And I do recommend also considering/responding to Jaroslaw's questions,
perhaps your design is needlessly elaborate and out of step with the
actual requirements. Good luck.
