SMTP Authentication

I have installed the POP3 connector for exchange, and incomming mail is
working fine.

However, for outgoing SMTP mail, my ISP requires authentication.
Trying to send mail from my outlook clients, gets an error - "relaying
prohibited."

If I use outlook express, I can turn on authentication for the client and it
works fine.

How do I turn on authentication in exchange server ?

If I installed Internet Mail service on each of my Outlook clients, then I
can add authentication here, but that bypasses exchange server, and I loose
logging and control.

Can anyone offer any advice ?

You can configure the IMC to use DNS and send email straight to the
recipients mail server, instead of sending ap to yuor ISP for them to
deliver

Thanks Mal

Are there any resource issues doing it this way
(I'm working via a dial-up account with dynamic IP)

I'm back at the site later this evening, and I'll give it a try.

In Exchange Administrator / Connections / IMS / Properties / Security tab.
Edit the <default> entry, change to SASL/SSL security, tick the SSL/AUTH box
and click the Change button to enter your user name and password.

OK your way out, and restart the IMS.

I dont have an SBS or Exchange box in fron tof me, but it is not hard to
find. On one of tabs for the IMC there is a setting for "Use DNS" or "Send
Email to XXXXXXX host". It's not hard to find.

It seems this will not work over a Dial Up Network, as exchange server tries
to
resolve the DNS before the modem dials. Reading what Exhange Books I have,
reserves this implementation for Leased line connections.

I though this was my solution, however, I'm not working with individual POP3
accounts,
so I am not sure as to what username and password to enter here. I assume
that if it
was a global POP3 account, I would just enter the global postbox details.

My ISP does not support a global POP3 Account.

POP3 is not relevant for outbound mail. Your exchange server handles the
outbound smtp connection. The details I gave were relevant for configuring
the single user name and password required for outbound smtp authentication
organisation-wide.

If your ISP wants you to use the POP account details to authenticate
outbound smtp, and you have multiple accounts, then any one set of account
details should work for the outbound smtp authentication. If you take this
approach, you will need to check that outbound mail still has the correct
From when it is received (and has not been substituted for the account whose
credentials you're using).

Alternatively, you could change over from "deliver all mail to:
xxx.xxx.xxx.xxx" to "deliver all mail using DNS" which would cut your ISP
out of the loop.

Hi Steve,

We have a cable modem for our SBS Server (direct NIC)

I was just wondering if utilizing DNS can be effectively used, especially if
one is in India....it may seem a stupid question, but I bet you that our
provider (using leased lines by the Govt. Internet entity) would mess it up.

It's just a risk that I wouldn't take, and I would go through our U. S.
webhost....

Any comments?

Thanks,

Dorab

PS: I posted in another thread, and maybe you have an answer to this:

Can we set exchange to download mail through our webhost mail accounts, and
route the mails to clients on the internal network? I understand that this is
normal method of doing this, but with the lack of Microsoft documentation, it's
difficult.

Right now we are getting outbound mail, no problem, but our inbound requires
authentication from a POP account (which would be used by SBS's **exchange
server**...Is this possible? Thus, it requires the ability to input a Username
and a Password, even while connected to a cable modem on a second NIC. We have
been using DHCP with this NIC and the cable modem, but now we have received a
static IP, and have to reconfigure a new server.

Thanks in advance!

Man, I was looking for this a while back, but have switched to an ISP that
doesn't require it (yet).... is this applicable to SBS4.5 and Exchange 5.5, or
is it SBS2000 only?

I can't see any problem with you choosing to "deliver using dns", as long as
your server has at least one external dns server configured. Configuring
multiple dns servers will protect you against an individual dns server
failure.

To get mail from POP accounts into Exchange Server, you need a POP
connector - MS do a free one just for sbs which has some limitations if
you're using multiple accounts, or there's various 3rd-party ones available
to purchase (of which popbeamer seems to get the best press in this ng).

You key in your POP account details on the POP connector and it collects the
email at intervals and then submits it to Exchange using a standard smtp
connection.

This applies to Ex5.5. It is more clearly visible in Ex2K (marked as
outbound security) in the SMTP connector and SMTP virtual server.

That is a problem. I have one site running RRAS as a DOD router, it works
OK with Exchange, but IMHO it's a kinda messy setup. I have the POP3
connector calling a batch file, it just does a ping and waits for 60 Secs.
If you try to let RRAS DOD when the POP3 connector fires it will just time
out. These days if a customer wants an SBS setup, we just tell them they
need a 24x7 modem connection as a bare minimum, the POP3 pickup has too many
quirks and limitations.
