It bounces back with message 550 Host Unknown. We can send mail to this mail machine from the local machines. We have no idea as to why it happens and how to debug this problem. We discovered that sendmail.cf was updated once but sendmail.fc was not. The sendmail manual says it has to be manullay updated. Now that sendmail.cf is an ASCII file and sendmail.fc is a binary file, how can one go about it? Thanx very much in advance. chitale@cs.scarolina.edu
