I have everything working pretty well when I mail from the 486 to the RS/6000, but when I try to go the other direction the mail hangs up in the mail queue on the 486 and says: Mail Queue (1 request) --QID-- --Size-- -----Q-Time----- ------------Sender/Recipient------------ AA25063 5 Mon Jun 24 13:33 (Deferred: Host Name Lookup Failure) If I run /usr/lib/sendmail -q -v as a non-root user the mail gets delivered properly. Can Anyone give me some insight on what Deferred: Host Name Lookup Failure means and how I can fix this. Please E-mail all responses: Thanks, Bryan -- Bryan M.
