make

$ cd mailx
$ make

# make install

# make UCBINSTALL=/usr/bin/install install

$ ln -s /usr/local/bin/mailx /usr/bin/sendmail

OR 
$ ln -s /usr/local/bin/mailx /usr/lib/sendmail

test

$ smtp=upstream mailx name@mydomain.com

initialisation configuration file

if you prefer you can add SMTP to your mailx initialisation configuration file

# tail /etc/nail.rc

set autocollapse

# Hide some header fields which are uninteresting for most human readers.
ignore received in-reply-to message-id references
ignore mime-version content-transfer-encoding

# Only include selected header fields when forwarding messages.
fwdretain subject date from to

set smtp=upstream

this should prevent CPU going to 100% if you forget to specify a valid SMTP server
