Is there a programmatic way to test the existence of an email alias when logged in as an IMAP client from a remote host rather than sending an email or having to parse the aliases file on the mail server?It is a Postfix mail server.Edit: I found an example of email validation over SMTP and this looks like what I need. However on my server SMTP does not allow relays and I get a 554 for valid addresses. I'm wondering if there is an example like this one but for an SMTP server that requires authentication?
