Windows Server - converting from POP3 connector to SMTP

[feenster99]

Hi all,
I'm looking at changing our organisation over from a POP3 connector setup to receive mail via SMTP.

Can anyone give me a step by step guide as to what needs to be done to make sure we don't loose any mail? I'm guessing at the least, i'll need to change our MX records to point to our (static) IP address (do I change both MX records, or leave one pointing our Web hosting?). I'm happy setting up Windows Server to receive the mail properly, but I remember reading that I need to setup a PTR record with our ISP. Is this correct?

Cheers,
Matt

Hi,
Thanks for the reply.

I thought the reason for the PTR records was so that if your internal mail server was down, the mail would be bounced back to your ISP, who would hold it for a set length of time. Otherwise, how would the mail know where to be routed to if the internal server was down? Also, do you need to setup Exchange in any way to check the ISP's mailserver every so often, or is just pushed to you automatically?

Cheers,
Matt
