According to fetchmail's man page smtpaddress adds the domain to the 
rcpt to, not to the helo of the envelope.

Have a look at your /etc/hosts. Does the address 127.0.0.1 resolves 
first to the name of the machine or to localhost as is usually the case 
by default ?

If localhost is the first name, could you rewrite /etc/hosts to put the 
machine name (what you want to see in the helo) as the first name 
matching 127.0.0.1 ? Something like:

127.0.0.1   machinename.domain.dom   machinename  localhost.localdomain  
localhost

My guess is that localhost may be the first name matching 127.0.0.1 and 
fetchmail uses it in the helo.
