smtp.myserver.com and pop3.myserver.com ? i only made a mail.myserver.com and it's an mx record pointing to my exchange server. inside the office network i put mail.myserver.com in for pop and smtp. send and recieve work fine. but the remote office's mail.myserver.com works for pop3, but for smtp it only works when sending to other exchange mailboxes. outbound mails bounce back. i know we could use the isp smtp server, but what about the sprint wireless cards for the remote laptops? and what about when they go home? do i have to set up 3 different profiles in their outlook? is there any way i can make their outlook smtp and pop3 mail.myserver.com and it work anywhere? there is a vpn tunnel but i haven't even started looking in to configs for that. any advice/guidance is greatly appreciated. what exactly is involved in creating my own smtp.myserver.com and pop3.myserver.com? can they point to the same server or do they need 2 separate static IPs?

Thanks. We'll let you know when a new response is added.

You can have the same IP for both servers. I personally use mail.myserver.com for both smtp and pop for ease of use. Make sure you have an A record for mail.myserver.com as well as the MX record. Make sure you have port 25 open for smtp on the firewall. You will need to make sure smtp requires authentication to avoid the spammers relaying through your server.
If all of these conditions are met, you will only need one profile in outlook pointing to mail.myserver.com for pop and smtp.

    Inside of the network that works just fine. But outside of the network, at our other office, that setup will only send and recieve mail from other exchange users. You can't send to somebody@hotmail.com or etc. I guess they're just going to need to use the ISP's smtp server

    I misunderstood the not being able to send part. You need to set Exchange to relay through the ISP server. In ESM go to Servers|Protocols|SMTP and right-click on Default SMTP Virtual Server and select properties. Go to the Delivery tab and then select Advanced. Insert the ISP server name in the Smart Host box.

    Thanks, but it's already in there. Should the FQDN in there be my mail.mynetwork.com ? or should it be the FQDN on my actual domain? i also set up the smtp connector to point to my isp smtp server as well
