fyi
The following setup appears to be working in test at this time. It is designed to handle virtual domains with one alias file.
The virtual domain alias file must have one line for each domain name, corresponding to the default delivery address for that domain.
aaa.com: joe@???
Additional lines for each domain name may be present, and if incoming mail matches one of the specific lines, then mail is sent to the corresponding address on that line.
In addition, any email address at a virtual domain can be expanded into 2 or more addresses via a second alias file.
My thanks to Philip for the coding, and everybody else who figured this out and posted the clues.
