In sendmail this is controlled by the sendmail configuration files.
The following is an excerpt from my sendmail.cf

 
# class E: names that should be exposed as from this host, even if we masquerade# class L: names that should be delivered locally, even if we have a relay
# class M: domains that should be converted to $M
#CL root
CE root
CMpstat.com
 
# who I masquerade as (null for no masquerading) (see also $=M)
DMpstat.com

-------

I believe it is the CM and DM controls followed by the domain name
which solved this problem for us.
