Thank you very much Victor, it works now.
I did a mistake writing this mail, of course domain names should be enclosed
with slashes and dot escaped.
However I could not find in the doc this way to stop recursion. It's
perfect.

Thanks again and sorry to have thought it was a bug !

The above lines violate the documented table syntax. In addition, virtual
alias rewriting applies to *ALL* domains, not just virtual alias domains.
So the above is not going to work the way you want, even if expressed
correctly.

this will not work as written. And does not even require regexp tables,
which
make this unnecessarily complicated.

Virtual expansion is recursive, and your approach is fundamentally flawed.
With indexed files (hash, btree, ...) use:

        # Catch-all with identity mapping for RHS to terminate recursion
        domain catch-allother-domain
        catch-allother-domain catch-allother-domain

        # Exception with identity mapping for RHS to terminate recursion
        exceptiondomain exceptionother-domain
        exceptionother-domain exceptionother-domain

for each domain in question.
