OK here is the first problem. You _don't_ have mydomain listed under
mydestination. Move it from virtual_alias_domains to mydestination. (This
assumes that you deliver mail to local mailboxes, which I believe is true
but you haven't confirmed).

Again with the same assumption, move any reference to mydomain out of
virtual_alias and any aliases to _real_ accounts into /etc/postfix/aliases

No, the idea of virtual_alias_maps is that it translates virtual aliases
to either virtual mailboxes or other addresses for example,
sales at virtdomain.com becomes salesman at internal.virtdomain.com (So you can
run MailScanner as a gateway in front of Exchange or Notes for example).
For anything local, you must use proper shell accounts and the aliases
table (Where domains are not listed). Some times users don't want/ need
shell accounts so you can use virtual_mailbox_domains for these, this
needs more setting up to do correctly, but it's not too tricky. Speak to
me off list if you want help with that).
