using MX records with sendmail on RS/6000's

[Richard A Johnson]

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 at 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.
