Just in case anyone is wondering. With the "Sunset" of Prodigy Classic, people who signed up for PI have had the option to forward from the old ".com" address. This is supposed to last at least one year.

In my case pporro@prodigy.com gets sent to pporro@prodigy.net and there is nothing on the old system. So when Oct 1st comes along and Classic is no more, mail should still go through.

On the other hand, it appears that people who dropped the service, do not have any mail forwarding from old Classic. So it could just go to the mailbox and languish, or with any luck, get bounced back.
