Exchange
- SMTP
- Configuring the IMC/IMS -
This an extremely large topic,
but we will restrict the discussion to the required or
pertinent items.
For those of you with a historical interest, the Internet Mail Service (IMS) was originally called the Internet Mail Connector (IMC). This change, in Exchange 5.0, reflected a shift of some of the functionality into the Store process where it resides still. There are still vestiges of the old name sprinkled about however.
The initial configuration is now
provided through a Wizard.
| 1. |
|
Select
File/New Other/Internet Mail Service. It will point out
the prerequisites for using the service. Pay attention -
they really are requirements. |
| 2. |
a. |
If you will be
doing Dial-Up as opposed to having a permanent connection,
check the "Allow Internet mail through a dial-up
connection" box on the Server Selection page. |
|
b. |
If you
selected "Allow Internet mail through a dial-up
connection," you will be presented with a choice of
which RAS phonebook entry to use.
Note: Some people have had problems with phonebook
entry names longer than 20 characters or that contain
spaces. |
| 3. |
|
Select how to
route outbound mail. The default is to use DNS for
dedicated connections and to forward mail to the ISP host
for dial-up connections. These are the best choices. |
| 4. |
|
Select which
internet mail addresses will be routed through this IMS.
Except in rare circumstances, you should choose "All
Internet mail addresses." |
| 5. |
|
Specify how
you want the default domain name to appear on your
outbound mail. By default, it is set to "@<sitename>.<orgname>.com".
Your <orgname> may not match your registered domain
name. Most people will want to change this to "@mydomain.com". |
| 6. |
|
Select the
administrator mailbox. |
| 7. |
|
At this point
the Wizard is finished gathering information and needs to
install the service. It will need to do this as the
Exchange Service account you defined, so you will need the
password for that account. |
| 8. |
|
Press
"Finish" and off it goes. |
| 9. |
|
If you are
doing dial-up, then you will want to go to the IMS
properties and set a couple of parameters: |
|
a. |
On the Dial-Up
Connections tab, set the schedule you wish to use, and
configure the Mail Retrieval options. For more information
on mail retrieval, see our
Dequeue
page. |
|
b. |
If you are
connecting over a slow line (33.6 or less) you probably
ought to tune the connections parameters. On the
Connections tab, select "Transfer
Mode/Advanced". You should set the maximum number of
inbound and outbound connections to one each. You should
increase the maximum number of messages sent in a single
connection to a higher value, such as 50.
On an ISDN 64K or 128K
link, you might want to tune down the Outbound connections
number to 4 and increase the number of messages per
connection to 20. |
|
c. |
A
clarification of the "Time out after __ min" parameter:
This is an idle
time counter. After the SMTP traffic stops, this much idle
time will stop the connection. This is good in that it
will not abort a large message in transit. It may be bad
for you if you have a very busy site and there is never an
idle period that long.
We have received some
feedback that this may only apply to outbound messages.
The inbound messages can get cutoff due to the timeout.
|
|
d. |
A
clarification of the "Logon Information"
settings:
Use the Logon Information
property page to set a password for the destination
location of your dial-up connection. Alternately, you can
specify a RAS post-connection script and include logon
information there. You should specify logon information in
either this dialog box or use a script, but do not use
both.
|
| 10. |
|
If you have a
permanent connection and are running 5.5 SP1 or later, you
should configure the Anti-Relaying rules to be a good
Internet citizen. It is in the release notes, but we
will try to add more on that here soon. |
The list of required fields here is pretty
short. You need to define the Administrator's Mailbox and an Address Space.
| 1. |
|
Set an administrator mailbox. |
| 2. |
|
Create a new Internet
Address Space with a value of "*" (no quotes). |
| 3. |
|
Configure the Connections
page. |
|
a. |
We
usually recommend
"Forward all mail to host:" be set to the IP address of the
ISP server. |
|
b. |
Select "Dial
Using" and choose your RAS/DUN phonebook entry. |
|
c. |
Select "Transfer
Mode/Advanced". You should set the maximum number of inbound and
outbound connections to one each. You should increase the maximum number
of messages sent in a single connection to a higher value, such as 50. |
| 4. |
|
Configure the Dial-Up
Connections page. |
|
a. |
Select the schedule you want. |
|
b. |
Set the "Retrieving
Mail/Type Command:" value to the .BAT or .CMD file that contains
the commands to dequeue your mail from your ISP. |
| 5. |
|
Set the IMC service to
Automatic startup in Control Panel/Services. |
