man fetchmail

<hier noch ein vielleicht hilfreiches Zitat>

You should probably set up a few things in your
fetchmailrc file so as not to bounce mail (people
wouldn't understand the bounces anyway,
since they'd be from somewhere different to
where they sent the message or as you say
most is spoofed).

set no bouncemail
set no spambounce

You can also add an antispam option to
each of your poll lines, specifying the
postfix return codes which should be
treated as an antispam rejection.

poll
...
...
antispam 554

replace 554 by the return code(s)
for which fethcmail should drop mail.

You should keep an eye on your logs
to see if anything you wanted disappears
down this mail black hole. You'll need

set syslog

You can also designate an email address
to receive fetchmail bounces (other
than antispam bounces).
