Not necessarily.

This is not uncommon, regardless of who administers the virtual mail
servers. Some choose to do the virtualization IP-based (and this is
what the code in virtual.c supports), some do it name-based (requiring
that POP3 usernames of the form user@...ain are used).

It's the only way it's meant to be setup. Your use of "127.0.0.1" is
a hack. I'm not sure why it even works for you (all connections are
somehow tunneled via localhost?)
