iis smtp nntp: Possible, yes. But i would not recommend it.

First of all, more and more ISPs block port 25 (the client's ISP). So it
will be completely impossible for your laptop users to send an email in
some occassions. And I suppose you need a working solution for all your
clients.

There is however another problem using a local SMTP server. The remote
SMTP servers will (most likely) consider your laptop users to be spam
hosts. This is because they will be sending from IPs that is not supposed
to operate as SMTP servers (dynamic IPs, blacklisted IPs), and the remote
server will therefore think that the laptop's SMTP server is used to send
spam. So some of your emails might not get to the receipient.

I would implement a VPN solution. Another possibility is to require
authentication, and make it possible to access the SMTP server from
outside your firewall. But this will still not work if the ISP block port
25.

You can also use a webinterface for sending emails.

SMTP from laptop

Is there a way to use the SMTP on a Windows 2000 Pro laptop to send email ?

Our SPAM protection (Postini) dictates that no one use our SMTP (Exchange)
server to send mail, unless they are within the domain.

So someone "on the road", can get their email easily, but cannot send
without using another server.

Most get around it by using their "personal" email (like Comcast) account,
but what if they don't have a "personal" account ?

Can the SMTP service be set up to allow incoming from our server, and
outgoing through their laptop ?

Thanks in advance

JM

Sure. Install SMTP.

Well, not really. But your administraor may have configured it that
way.

Then you need to address the issue of sending through your Exchange
server for authenticated users, which is quite possible and normal.

In your situation, they wait until they get back to the office.

SMTP doesn't provide your client access to the mail anyway, that's
POP. And it's quite possible to use different POP and SMTP systems.

What will be an issue is that many destination SMTP servers will
refuse your emails as SPAM. Your best bet is to allow SMTP to your
Exchange Server from outside, possibly by using Outlook Web Access or
VPN if tight security is the driving force.

FWIW, we use Postini and I can send emails remotely with no trouble.
