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. You do not indicate what machine you are using, what version of Sendmail you have, or what sendmail.cf you are using (perhaps one from the cf/cf directory in the standard distribution?). All that aside, you may have found the 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? The sendmail.fc file is known as the "frozen configuration file". To rebuild, as root execute the command "/usr/lib/sendmail -bz". -- Mark Towfigh, Racal InterLan, Inc. towfiq@interlan.Interlan.COM W: (508) 263-9929 H: (617) 488-2818 uunet!interlan!towfiq "The Earth is but One Country, and Mankind its Citizens" -- Baha'u'llah
