Please describe the network layout between:

 - clients sending & receiving mail
 - the "mail gateway" running sendmail and MailScanner
 - the Zimbra server
 - the Internet connection

What's most important is to explain the route email takes:

1 - from a client, via MailScanner, to the outside world

Our client email touches the following systems in this order:

Zimbra -> sendmail -> MailScanner -> internet gateway or quarantine

2 - from the outside world, via MailScanner, to the client

Internet gateway -> sendmail -> MailScanner -> Zimbra or quarantine

If the email originated from our clients, the message is stored and can be
viewed or released from within MailWatch (1.2.9)

If the email originated from outside our domain, the message is logged in
MailWatch, but cannot be viewed or released.  I searched the quarantine
folder for the message ID and found nothing stored.

Regards,

Antony.
