 I have used sendmail.mx on a Sparc with no difficulty.  But you have to use
sendmail.mx.  You cannot use sendmail.nomx even if the resolver code is in
the shared library.

 I have seen your problem before.  It is usually caused by not understanding
what it means to run sendmail.mx

 I recommend you do the following:

	cd	/usr/lib
	mv 	sendmail	sendmail.nomx
	ln	sendmail.mx	sendmail

I don't know why Sun doesn't distribute their systems with both a
'sendmail.mx' and a 'sendmail.nomx', with one of them linked to sendmail.
(Please Sun, would you consider doing it this way in future.  Maybe even use
a symbolic link instead of a hard link.  Most sysadmin's are not sendmail
guru's and are very hesitant to move files around.  Put them in the right
place to start, so that it is easy to understand.)

 It is NOT ENOUGH to start 'sendmail.mx' as the daemon from /etc/rc*.
The actual binary /usr/lib/sendmail in use MUST BE sendmail.mx if you
want this to work.  Most outgoing mail uses /usr/lib/sendmail, while
incoming mail uses the daemon.  It is for the outgoing mail that you need
sendmail.mx

 You should be able to build sendmail-5.65+IDA using Sun's libresolv.a.
