configure your /etc/mail/sendmail.mc file:

define(`SMART_HOST',`server.to-send.mail.to')

I also use the following because my server accepting mail runs on a
non-standard port:

FEATURE(`mailertable')dnl
define(`confRELAY_MAILER', `esmtp')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 0000')dnl

(I had to create, and make my mailertable.db file after making sendmail
modification)

makemap hash mailertable.db < mailertable

After editing sendmail.mc run, make -C /etc/mail, and restart the sendmail
service.
