Have you looked in the /var/log/maillog or /var/log/messages for additional information. This could also be a DNS issue, where the Yahoo mailserver attempts to perform a reverse lookup of the sending server. The other thing that you may want to do is use your ISP's mailserver as a "smart relay". This would require modifying your /etc/mail/sendmail.cf file. Marcus O.
