Since 10/2/12 I've [and others] been unable to SEND mail via ANY of the AT&T servers [outbout.att.net, pop.att.yahoo.com, etc.] . I can receive mail fine, but I've had to send mail via another acount. I've seen other posting where almost all other users of Apple Mail [version doesn't matter] are having this problem as well as users of other client; Why can not this problem be resolved?
