I would say the most reliable way would be to just parse
/var/qmail/virtualdomains and compare the LHS with $HOST (although this
is a problem while somebody has updated virtualdomains but haven't sent
-HUP to qmail-send yet). Do you just need to test for these three packages
or does it need to handle all types (for example, maildrop has its own
virtual users mechanism)? How reliable does it need to be?
