This is fine,but I'm not using local users directly. I'm using virtual
mailboxes and virtual domains. I have a customer who owns several
domains and wants individual mailboxes for each domain. So, I have set
everything up for that using /etc/postfix/vmailbox with entries like:
johndoe at domain1.org domain1.org/johndoe/
janedoe at domain2.org domain2.org/janedoe/
so that I do not need to create/manage so many local user accounts. The
problem is how I alias 'jane at domain2.org' to 'janedoe at domain2.org' with
this setup. It's completely eluded me so far.
