Hmm. I haven't really done much with virtual domains, so others will
probably have more experienced advice to give, but wouldn't it make more
sense to have an alias file per-domain. What I write below is untested
and is being written WITHOUT the documentation. So I probably have all of
the option names wrong and several other bugs.
# A director, probably relatively early in the list of directors.
virtual_aliases:
domains = lsearch;DIR/virtual.domains
driver = aliasfile
file = DIR/{$domain}-aliases
The file virtual.domains would just list domain names.
metainc.com
foo.bar.com
whatever.org
and then you would have an aliases file for each, so the file
metainc.com-aliases
would contain
bob@???: bob@???
adam@???: adam@???
Again, note that I probably have the details wrong. But I think that the
over all strategy will give you a more robust system that is easier to
maintain.
