I'm following the instructions for installing Sendmail 8.12.1 for MPE/iX. Am unable to get past the DNS configuration check which reports that it can not find the DNS "PTR" record.

I've tried using nslookup.pubxl.telesup to see if there is a problem there but when I pass it (one at a time) <ipaddress>, <host name> and the <fully qualified domain name> it returns the correct values.

My network guy has used the same setup this time as was used for our Windoze servers. They work so why not the HP?

I haven't had a chance to check if he's added the HP to both of the dns servers. If thats not it the "What is wrong"?

The output from dnscheck (real names and ip's replaced with text between <>) follows:

---------------------------------------------------------------------

Looking up matching DNS "PTR" records for <myhp ip>... no

Either no DNS "PTR" records were found for <myhp ip>, or PTR records were found but
didn't match <myhp>.<mydomain>.  This is a serious problem; 
double-check /SYS/NET/RESLVCNF and ask your DNS administrator whether or not 
your e3000 exists within the DNS database, and then rerun this script after
correcting any problems.  Here are the results of the failed dig query:
