Like this:

 set postmaster "postmaster at morannon.homelinux.org"
 poll imap.gmail.com with  
  proto imap
  user "johannes.graumann at googlemail.com"
  pass "<I'M NOT TELLING>"
  is "johannes.graumann at morannon.homelinux.org"
  here
  no keep
  ssl
  smtpaddress "morannon.homelinux.org"
  limit 100000000
  mimedecode
