    Re: POP3 HELP (FPXP)

    Your e-mail service usually is through your access provider, but it also could be through your web hosting provider (and they might all be the same company).

    Just to give you a brief overview of how e-mail works, the sender shuffles the message off to its SMTP server, which then contacts your SMTP server. The process requires numerous steps: (1) the domain name in the address is checked in the domain name system to get the numeric address of the name server that knows what to do with mail for your domain; (2) those name servers provide an address (using MX records) for the SMTP server that receives your mail; (3) the sender's SMTP server contacts your SMTP server, which then checks to see whether it is authorized to accept the message (usually it is only going to handle messages for local accounts and not be a middleman); (4) your SMTP server stores the messages in a manner that you can access using the POP3 protocol.

    Now, as you can imagine, if you change mail providers without updating DNS, your mail will not find you. Servers around the 'net cache DNS information for a specified period to reduce the millions of lookups that otherwise would have to happen, which causes timing problems whenever you change that information. Typically it's best to do this during periods of low traffic, such as Friday night, and only after you have run with a short TTL (time to live) on the DNS records for a time to minimize the amount of time old information will be cached. Even then, there is a lot of stress involved. Nothing worse than people thinking you're out of business because you lose e-mail for 72 hours.

    What I suggest: Contact whatever provider you want to handle your e-mail service and have them do the heavy lifting of the switchover (assuming it is necessary). This is your first opportunity to test their competence. If they don't understand the issues or have a standard way to deal with it, you might want to find a slightly less cheap provider that knows what it's doing.

    Hope this helps.
