[fetchmail]oversize email notice, fetchmail-daemon(_at_)localhost, smtpa

Hi all,

I'm having the same problem as described in this thread
http://lists.ccil.org/pipermail/fetchmail-friends/2001-June/000735.html

I'm using Courier-MTA on RedHat Linux 7.2 which doesn't like
'FETCHMAIL-DAEMON(_at_)localhost' as the envelope sender (localhost is not
fqdn). This fetchmail-daemon address is generated by fetchmail for
oversize emails notices. I can't seem to convince fetchmail to use
'smtphost' or 'smtpaddress' option instead of plain 'localhost'.

My questions are:

- Why does fetchmail insist on using 'localhost'? Using the value of
  'smtpaddress' seems more reasonable to me.

- Before I dig into the sources myself, anybody ever hacked the source
  to do this (tell fetchmail to use 'smtpaddress' if available instead
  of 'localhost')? or maybe has a pointer on where to start?

Thank you for your time.

Regards,

Ronny
