The virtual server name is in fact a regexp, so that the same rules
may apply to several servers. In the example, the servers
\"my3server\" and \"my4server\" both use the same rules. Similarly,
the inbox string is also a regexp. The actual splitting rules are as
before, either a function, or a list with group/regexp or
