AIX sendmail problem

[Charles Derykus]

I've run into a problem mailing to host "777sup1" in our domain. 
Both sender and recipient are AIX RS/6000's running 3003 and using DNS.
I've included a debug session below: 

	> /usr/lib/sendmail -v </dev/null guest at 777sup1

          ced... setsender:  uid/gid = 200/1
          guest at 777sup1... Connecting to 777sup1.ca.boeing.com.tcp...
          guest at 777sup1... Connecting to 777sup1.ca.boeing.com (tcp)...
          777 up1.ca.boeing.com Sendmail AIX 3.1/UCB 5.61/4.03 ready at Wed,
          27 Mar 91 10:41:02 -0800
          >>> QUIT
          221 777sup1.ca.boeing.com closing connection
          guest at 777sup1... Deferred: Bad file number


I note that sendmail on "777sup1" has apparently munched the
"s" in its hostname as evidenced by the line:

	"777 up1.ca.boeing.com Sendmail AIX...."

Other names with 3 initial digits suffer the same fate.

Any advice greatly appreciated.
