hello folks,
i recently installed exchange 2010 in a 20 user office. they are using hosted emails. we had to setup pop3 mail puller to download the email and send from exchange. all went well, i havent brought any user onto the domain yet. just two test users. I am also using relaying through relay.dnsexit.com as they do not have an mx record setup. What is happening is that the queues are filling up with tremendous amount of relays from all the people who are still using pop3 directly to their outlook client. I have added all users and created the mailboxes with the pop3 details pertaning to the hosted pop3. but none of the users have joined the domain. Now i dont know how these email are getting generate and then relayed. We were actually blocked by our relaying (dnsexit) as we exceeded the amount of allowable relays per day.
any suggestions what can i change???? kinda out of ideas
Cheers
Exchange Rocks
