Yes, from the manual: 
http://mmonit.com/monit/documentation/monit.html#setting_a_mail_server_for_alert_messages

                Monit, by default, use the local host name in SMTP HELO/EHLO 
and in the 
                Message-ID header. Some mail servers check this information 
against DNS for 
                spam protection and can reject the email if the DNS and the 
hostname used in 
                the transaction does not match. If this is the case, you can 
override the 
                default local host name by using the HOSTNAME option:
                
                set mailserver mail.tildeslash.com using hostname 
"myhost.example.org"
