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.
