Mark and Hay; Sorry had do do some work for cleints and turned attention away from mailserver problems for a few hours.........It seems like these remaining probelms can be solved through configuration repairs since most parts of MTA and Postfix are working ok now........
Status:
1. Internal local mail is being sent and delivered ok.
2. Outgoing (outbound) Mail to internet address is being sent and delivred ok.
3. Local Mail cleints can connect to PostOffice and See mail and archives and folders in IMAP ok.
Not Working: Inbound Mail from Ineternet is being queued but not delivered. I haven't made any chnages to main.cf to address aliaises errors since 2:00pm EDT; waiting to see if the situation clarified itself....
