I am using a upstream, 3rd party anti-spam/virus filter. Thus all MX records point to that filtering server which then forwards "clean" e-mails to my ME Ent 3.52 server. To avoid spam from coming directly thru the "back door" into ME server, I have enabled "Any emails to this postoffice must come from authenticated connections" for the customer mailbox. This mailbox accepts mail for multiple domains. I have also placed the upstream filter IP addresses in the SMTP Privileged IP list. The upstream filter is set up to accept for both domains too.
Mail sent to the real domain name (realname.com) works fine. The problem is that any e-mails sent to the aliased domain (myalias.com, below ) name are now rejected with a:
<myname@myalias.com>: host mail.realname.com[xxx.xx.xxx.95] said: 503 This mail
server requires authentication when attempting to send to a non-local
e-mail address. Please check your mail client settings or contact your
administrator to verify that the domain or address is defined for this
server. (in reply to RCPT TO command)
If I remove the "...must come from authenticated connections" then mail goes through fine - along with spam that circumvents the upstream filter.
Is this a bug, or some other ME setting that I am missing here?

Are talking about the feature to force authentication on the Security TAB (Prevent sender spoofing) or the feature under the inbound tab?
Can you show us the SMTP debug log extract for a time when a send fails?
