Unable To Access E-mail, With Outlook, Through Port 25, AT&T

After hours on the phone with AT&T techs, we’ve come to find that AT&T is block­ing port 25. AT&T’s doing this in an effort to curb spam, and unso­licited Emails. If you’re hav­ing this issue, we rec­om­mend you call AT&T and have them unblock the port. Keep in mind that AT&T now has two divi­sions, U-Verse and DSL. Be sure to call the cor­rect department.

AT&T DSL Sup­port 1–877-722‑3755
U-Verse sup­port 1–800-288‑2020

    Just a help­ful hint.

    ATT is no longer unblock­ing Port 25 for Reg­u­lar users. If you need port 25 unblocked you have to upgrade to a busi­ness account.

    If you use their info you can get your email with­out look.
    –Incom­ing Mail Server(POP3): pop.att.yahoo.com
    –Out­go­ing Mail Server(SMTP): smtp.att.yahoo.com
    –Out­go­ing server (SMTP) requires pass­word authen­ti­ca­tion
    –Incom­ing Mail Port#:995, secure connection(SSL) checked
    –Out­go­ing Mail Port#:465, secure connection(SSL) checked
