I think this is your problem! I know recent versions of sendmail have 
better handling of resolving the local host. For me this disappeared 
after appending


to my but updating your sendmail version should also change 
that behaviour to something different, I think! Had problems with this 
also but do not know exactly how I got rid of. Maybe because I do 
sendmail updates regularly and this dissappeared somewhere after 8.12.7, 
I think.
