Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Matthias Andree reports :

fetchmail will generate warning messages in certain circumstances (for
instance, when leaving oversized messages on the server or login to
the upstream fails) and send them to the local postmaster or the user
running it.

If this warning message is then refused by the SMTP listener that
fetchmail is forwarding the message to, fetchmail crashes and does not
collect further messages until it is restarted.
