Re: Can I configure Exchange to ONLY accept email from my ISP ??

Hi Simon, by default at setup, MX record is at ISP / Domain host.

All the work is done by the ISP then, you just tell them when they scanned it send it onto your IP... dont think you will get any assistance though, they will say collect it by pop3.

Why you concerned about opening your IP for SMTP... no hacker can get in that door, port 25 wil only accept email requests. Just have to ensure you are not an open relay

Email communications are standard industry, you cant have your own system..Ports 25 and 110 (ssl are on different) Unless ISP has facility to utilise other ports, cant see where this will work.

Im trying to understand your logic, is there something you have done in the past for this to work ?

POP3 - no

MX record for our domain will be set to ISP's server

This also mean our IP is not exposed via MX

ISP will scan the email "Clean" mail will be sent to our IP

Hi Simon,

Mail delivered to your ISP, you collect via pop3, SBS pop3 not recommended, 3rd party better.

Have I missed something...;-) can you elaborate a bit more... ;-)

Technically, if ISP supports it can configure MX and A records to send email to ISP via SMTP this then hops over to your server but is additional configuration for something uneccessary. If trying to utilise ISP spam / virus capabilities then this would usually be available for pop3.

As I say, elaborate a bit more what you mean...
