Sbcglobal Email Configuration

Hi -

I'm trying to use my old SBCglobal.net email address with Outlook 2010, does anyone know if Comcast blocks ports 993 (inbound) or 465 (outbound)...?  Otherwise, if anyone has switched from ATT to Comcast and was using an old sbcglobal email address, I'd be interested to know how you got it going.

I can read my old sbcglobal email fine with a browser from the Yahoo.com website.  Unfortunately, I can't seem to use my Outlook now, which is a huge headache.  It seems that ATT started a new secure email key requirement and now that I am no longer with them, I can't seem to get this created either at the MyATT website or via Yahoo instructions.

Not sure if that ultimately the problem or what.  If anyone else is currently using Outlook and an old sbcglobal.net email address, I'd sure like to hear from you.

Thanks! -
