I'm in the UK so no AT&T. Also I don't use Yahoo Mail. However, I do see references to NEW Yahoo Mail and CLASSIC Yahoo Mail. I don't know the difference but perhaps your new account is under the new regime which has different servers or access policy? Just a thought seeing as nobody else has replied.

<P>I have been using Pegasus for a number of years and in that time I have had occasion to set up 6 or more e-mail mail boxes.  I say that to only indicate that I am more than reasonably familiar with the "how toos"</P> <P> Recently I wanted to set up a new mail box within an existing Pegasus program and on a new laptop without any other Pegasus mailbox..  I did all the things one normally does but when I go to get my mail in this new mail box on both computers I get a message that reads "The host claims that either the username or password you have supplied is invalid."</P> <P> My server is Yahoo.  The e-mail adress I am attempting to establish ends "@sbcglobal.net"  I am able to access the mailbox on YAHOO.COM without any problem yet from Pegasus I get the error message that sbcglobal.yahoo.com will not recognize the username and password.</P> <P> On the ATT page for POP3 and SMTP settings, they say that we are NOW to use pop.att.yahoo.com.  That does not work either.  I am presently using pop.sbcglobal.yahoo.com on existing mailboxes without any problems.</P> <P>When I attempt to send I get this -- <FONT size=2>Delivery has failed on the enclosed message for the following reasons reported either by the mail delivery system on the mail relay host or by the local TCP/IP transport module:</P> <P align=left mce_keep="true"> </P> <P align=left>334 535 authorization failed (#5.7.0)</P> <P align=left mce_keep="true"> </P></FONT> <P> Any suggestions as to how to get  this new mailbox established??????</P>
