You will need to edit /etc/mail/sendmail.mc and regenerate a new sendmail.cf
Edit and add a line similar to below for your network:
DAEMON_OPTIONS(`Port=smtp,Addr=90.0.0.2, Name=MTA')dnl

Generate new cf file by running macro:
#m4 /etc/mail/sendmail.mc > /etc/sendmail.cf

Restart sendmail and you should be good.
