Edit the tsm.cf file (in /etc/mail/ or similar) to include

FEATURE(relay_entire_domain) 

between the DOMAIN() and MAILER() lines. Since you're editing the file, you may want to also improve security with

define(`confPRIVACY_FLAGS',``noexpn,novrfy'')

This change is necessary because the WWW and MX servers for the domain do not exist in the same process space; this FEATURE triggers sendmail to process messages for the domain using it's external delivery mechanism.

The edited portion of the tsm.cf file should look similar to this:

DOMAIN(website.com)dnl
FEATURE(relay_entire_domain)dnl
define(`confPRIVACY_FLAGS',``noexpn,novrfy'')dnl
MAILER(smtp)dnl
MAILER(procmail)dnl
