One possible solution to this problem might be for L-Soft to change the
format of the envelope-sender address on the outbound probe.  Instead of
'owner-listname*bparker**POP*-EXAMPLE*[log in to unmask], use
'owner-listname+bparker**POP*-EXAMPLE*[log in to unmask] Plus-
addresses are supported by widely-used MTA and LDAP software.
