Hi,

We are using redhat linux 9. We have configured sendmail. We are able
to send mails but not receiving them. When we cheked the log we came
to know that there is an error "unknown host", "My unqualified host
name (mailserver) unknown; sleeping for retry". Log file has been
pasted in this message. We are not finding where we r doing wrong.
Please give us a solution.
