Hello,

I believe at&t now requires SSL connection to their servers. I also have had much trouble sending email using sendmail and other MTAs through SBC/at&t. SSL using port 465 (smtp.att.yahoo.com:465) seems to work best. They still answer on non ssl port, but I was unsuccessful sending email through it. Auth is still plain.

If I have time I will try to send using perl.
