    MX Record


    Hi everyone,
    Can someone please tell me is the MX record for a domain actually the IP address of the POP mail server, that is the address where emails for that domain are to be sent?

    Is that right? Thanks everybody

    MX records have nothing to do with POP3. All they have to do with is telling everybody where to send email to for a given domain via SMTP.

    Although, with the exception of high traffic services like yahoo and hotmail and such, the POP3 server is hosted on the same machine and IP as the SMTP server. This is purely convenience, not convention.

    So....


    Thanks,
    So the MX record is the IP address of the mail server for that domain?

    Correct?

    MX records points to domains, not IPs. The domain points to the mail server IP that is supposed to RECIEVE mail yes.

    Confused...


    "The domain points to the mail server IP that is supposed to RECIEVE mail yes"

    How does the domain point to the mail server IP? Whereabouts is this recorded?

    One final little thing, if I was to change over a domain to use other nameservers (changing all records including MX for that domain), how do I make sure I don't leave emails on the old mailserver?

    As there will be a point during propagation where some emails are going to one mailserver and some other emails are going to another mailserver. Correct?

    Thanks SilentRage.. you've been a big help.

    "How does the domain point to the mail server IP? Whereabouts is this recorded?"

    How is any IP recorded? With 'A' records! You'd have to have at least 2 records like the below:

    dollardns.net. MX 10 mail.dollardns.net.
    mail.dollardns.net. A 216.117.186.93

    "how do I make sure I don't leave emails on the old mailserver?"

    Well, if I were to change things over to a new IP, I would do something like this:

    dollardns.net. MX 10 mail.dollardns.net.
    mail.dollardns.net. A 65.98.66.26
    oldmail.dollardns.net. A 216.117.186.93

    That way email is sent to the new IP, but I can still login to retrieve my mail using the old IP by logging in to the POP3 server at the oldmail.dollardns.net domain. Once you stop getting mail at the old server, you can safely shut it down or terminate the service.
