I have a MailEnable mail server on my dedicated Win2003 box. For some reason I can't send emails to the individual mailboxes on at least one of my domains (though mailing lists work fine).
I get this error sending to mailboxes:
08/05/07 16:33:47 SMTP-IN [url removed, login to view] 344 [url removed, login to view] RCPT RCPT TO:<email address here> 550 Requested action not taken: mailbox unavailable or not local 66 28
No control panel (Plesk, etc) is installed -- I do admin thru Remote Desktop.
