I have a person here who is trying to use sendmail from his RS/6000 to deliver a mail message to a user at "compuserve.com" (e.g. <username@compuserve.com>) and is getting an error saying that this host isn't known. There isn't an A record for compuserve.com, but there are 2 MX records. My guess as the source of the problem would be that IBM's version of sendmail doesn't support MX nameserver lookups. Is this the case? Does anyone have a fix? (Other than "use MMDF-IIb" that is!) Thanks for any help anyone can provide. ----------------------------------------------------------------------------- Richard A.

Look at the sendmail.cf file - look for a like that reads #OK ALL there are some comments above it which explain what it does. Put simply, it enables processing of various types of nameserver records - including MX. Uncomment and change this line as appropriate and then refresh -s sendmail You may want to read through sendmail.cf and change a number of other flags. - Scott -- This is my signature.
