No problem. I use Entourage and SBCglobal. Just go to Tools > Accounts >
Mail and set up a new account (New). The entries for e-mail address and
Account name are the same (your e-mail address). The POP server is
pop.sbcglobal.net and the SMTP server is smtp.sbcglobal.net. That's it. You
can manually retrieve your mail (Send and Receive) and/or set up an
outomatic schedule (Tools > Schedules). You can add this account to the
existing Send and Receive All schedule.
Use pop.sbcglobal.yahoo.com for "receiving mail" and
smtp.sbcglobal.yahoo.com for "sending mail". If those don't work, call
SBC. They have good support.
