But their server has a retarded low send limit, which gives us
problems.

So instead we want to use our SMTP server at our webhost, BUT that
server requires authentication on a non-standard port.

How do I set that up in Exchange? I can only find an entry for the
server address, nothing about authentication or port...

Unfortunately we only have this one ISP in the area, and an
unrestricted line is not available for a minimum of 3 months yet.
They consider our line a "regular" ADSL line, meaning we suffer the
same low limits they give residential users.

I just went through all this myself. I ended up setting up an
account with dyndns.org for there Custom DNS, Mailhop Outbound, and
Mailhop Relay services. With this setup, I send and receive mail
through them, keep my dynamic IP update for domain name resolution,
they scan all mail for viruses and spam, and give reverse DNS entries
so places like AOL won't mark your mail as spam.
Anyway, my ISP blocks my incomming and outgoing ports so I had to
use alternate ports for both. I'm not good at Exchange, but found
enough to make this work. I think you need to configure this section:

Go to Server Management...
Advanced Management...
"your domain name" (Exchange)...
Servers...
"your server name"...
Protocols...
SMTP...
Default SMTP Virtual Server (right click on this and go to
Properties)
Delivery Tab of Properties

Ah. Close, but not quite...never do anything like this in the virtual SMTP
properties. Leave that stuff alone (revert whatever changes you made).

Instead, you do this in your SMTP connector(s). If you set up SBS using the
wizards, you've got one in there already. Run the CEICW to put in the
mailhop outbound server, then go into ESM and edit the connector to change
the port & the authentication.

There are three buttons on the lower part of this tab: Outbound
Security, Outbound Connection, and Advanced

Under Outbound Security, configure the security settings
(authentication method, username, password, etc...)
Under Outbound Connection, specify the TCP port to connect through
Under Advanced, configure your FQDN (ex. yourdomain.com) and specify
the smart host (the domain name of the mail server you're trying to
send through)

Hope this helps. If you are trying to also receive mail, you may have
the same problem that I did where they block your incomming port as
well. That can be configured to use another port as well. Post if you
need that info.
