[Zope] dtml-sendmail/smtplib.py

I'm new to zope/python so this may have been addressed elswhere but I did search the archives and couldn't find it Redhat7.0 Sendmail 8.11.0 Python 1.5.2 My First email form threw an error which I traced to this ... /usr/lib/python1.5/smtplib.py : line 303 name=socket.gethostbyaddr(socket.gethostname())[0] I ran it at the python interpreter prompt and it threw an error so I changed it till I got a hostname from it, the line that worked for me was name=socket.gethostname() I'm happy it worked BUT is this going to break other components of my zope system and/or python? Or is it normal to need to tweak this file for different versions of sendmail Thanks for any advice Kai Keliikuli
