I keep getting bounced email at nobody@myservername.com as follows:

------------------------------------------------------------
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

mkarls@domain.com
Child process of virtual_sa_userdelivery transport returned 70 (could mean internal software error) from command:
/usr/bin/spamassassin

The following text was generated during the delivery attempt:

------ mkarls@domain.com ------

Can't locate object method &handle_auto_report& via package &Mail::SpamAssassin::PerMsgStatus& (perhaps you forgot to load &Mail::SpamAssassin::PerMsgStatus&?) at /usr/bin/spamassassin line 217.
------------------------------------------------------------

Eventhough the Mail::SpamAssassin module is already loaded I have reloaded the one mentioned above on several occations, but from time to time I still get emails like that.

Any suggestions???
