iMS has the great advantage of being able to configure a group of servers to
act as a single server.
The CFX_iMSMail tag does not transmit mail via SMTP - unlike CFMAIL. What
it does is write a raw mail file and one or more control files directly into
the POST Server queue. The SMTP Server does not rely on the POST Server
which is why you can go to our web site or one of our resellers and order
one server by itself. Let's say you have two SMTP and two POST Server
distributed among 4 boxes. It would be something like:
SMTP1------------
|---Server1 (Storage/SQL)
SMTP2------------
POST1 (local storage)
POST2 (local storage)
Both SMTP1 and SMTP2 would share mail storage and the SQL Server. All
incoming mail would be stored on Server1. The POST Servers are used for
sending mail.
Analysis of incoming mail:
Incoming mail to the SMTP Servers can be from external mail servers or mail
clients (like Outlook). The incoming mail can be for a local recipient or a
remote recipient. If it's a local recipient then the mail is stored on
Server1 and a DB record is written to the SQL Server on Server1. If the
mail is non-local then the SMTP Server writes the mail to a POST Server
using either the SMTP Server "result=relay" action or using the CFX_iMSMail
tag. The CFX_iMSMail tag can be configured to send the mail to local
storage on either POST1 or POST2. You can determine which server gets the
mail in several ways. For wxample, if the receiving domain begins with "A"
through "M", send to POST1, if "N" through "Z" send to POST2.
