David Harris has implemented ESMTP AUTH CRAM-MD5 for WinPMail.  It does a SMTP authentication in accordance with RFCs 2554 and 2195.  It will also do the LOGIN and the strange MS AUTH=LOGIN.

Go to Tools | Internet  options | (Sending) SMTP, edit the SMTP configuration, select the "Security" tab and then select the SMTP Authorization option as specified by your ISP.  Most require the the second or third SMTP Authorization option

Im sorry if this is a repeated question, i'm afraid that I did not have much success searching the site for this answer.

I have been using Pegasus version 4.31 for obviously quite some time with an alltel.net email address. Recently alltel converted their addresses to windstream.net. I have gone in and made what I thought were the correct changes and can recive my emails but cannot send emails. This is the error message I have received...I would appreciate any help and am sorry if I ommited any necessary details for this issue.
