said by FureverFurry:I need to replace my PC and Vista is no longer available (mine preinstalled). Hence, no WinMail via Vista. Now if anyone knows of a LEGITIMATE (aka legal) source to buy Vista, please PM me.
I don't think that such a place exists at this time. Windows 7 is the successor to Windows Vista.
If you really liked Windows Mail, the successor from Microsoft is Windows Live Mail, which is a component of Windows Live Essentials, which is free to download from Microsoft. Or use Mozilla Thunderbird. Either is as good as Windows Mail. Either offers the choice between POP3 and IMAP.

Windows Live Mail

Mozilla Thunderbird
I did some filling for the Mozilla Thunderbird example; but these images are meant to show what tha clients can do. If you require the details, the secure ports would be:
IMAP: 993 w/SSL
POP3: 995 w/SSL
SMTP: 465 w/SSL
