I do have a domain created in zimbra called servername.domain.com, and an alias for
admin@servername.domain.com is setup as an alias on the
admin@domain.com account. Like I said, if I send an actual email message to
admin@servername.domain.com, it delivers fine and I can read it in my
admin@domain.com mailbox.. however, these virus quarantine notification messages are bouncing with "user unknown".
