        "Virtual users" and "aliases" mean two very different things, at
least in the Postfix and Exim communities.

Sendmail as well. Aliases are username-only (no hostname), and virtual users are names with domains (or wildcard domains), mapped to users (local or otherwise). THEN there's "virtual users" in the sense of one's POP/IMAP daemon, but even that should probably be managed through the MTA's virtual user mechanism (delivering the mail to the vPOP mailboxes).

        With Exim, a "virtual user" could be either a local account for a
"virtual domain" (meaning a domain for which the host takes email, but it
is not configured with that domain name in DNS)

Equivalent to sendmail "local-host-names".

or a user who does not have an actual Unix login account (as with Cyrus-IMAP).

This is what I apply "virtual user" to mean if it isn't specifcally qualified.
