I've been asked to admin an old, jumbled install of qmail/vpopmail (many
are local users, many are vpopmail users with .cdb). I'm having a brain
cramp because the install has domains splattered all over the following
My exercise is to identify ONLY those domains that the server will
actually accept delivery for from the Internet so that we can start
pruning away the domains that seems to be lingering with no
My intention/belief was that ONLY 'rcpthosts' and 'morerctphosts' govern
which domains the server will accept delivery/relay for from the
outside. Thus, I felt that if I built a master list from these two
files, any other domains I might find are automatically "unused".
However this install has a number of domains that are aliases in the
'locals' file to a single local account and the domains only seem to
appear in 'locals'.
Does 'locals' (or 'virtualdomains') in any way influence the relay
decision to accept incoming mail? Or am I right that ONLY 'rcpthosts'
and 'morercpthosts' define the permitted domains.
Sorry for the long explanation, validation/help is much appreciated!
