We looked at this before and did a workaround in the sendmail configuration. I did some more digging today and found the permanent fix. 

hostname -A will return a list of DNS reverse resolved (or /etc/hosts lookups) for all of the IP addresses listed in your network config. It appears sendmail uses that to get its FQDN default. Your /etc/hosts files had localhost.localdomain included in some of the boxes for the loopback entry. Sendmail ignores localhost - but if it finds localhost.localdomain - it often uses it.

I have edited those entries appropriately in your /etc/hosts files - and its all fixed.
