Subject: [Exim] recent problem with SA
Hi there!

My friend told me, he suddenly can't send mails over my server.
I updated spamassassin a couple of days ago, may be he triggered the
new behaviour now. I don't know, if the problem ist at SA, though.

Please take a look, its on my produtction server and not well
running. That hurts :/

Looking at the From: Headers I think this are messages, which would be
classiefied as spam normally. I reject if above 10 points.
Here is the (long well working) acl:

begin acl

#!!# ACL that is used after the RCPT command
check_recipient:
  # Exim 3 had no checking on -bs messages, so for compatibility
  # we accept if the source is local SMTP (i.e. not over TCP/IP).
  # We do this by testing for an empty sending host field.
  accept  hosts = :
  accept  recipients = postmaster@* : \
      *-admin@*
  deny    hosts = +rbl_hosts
          message = host is listed in $dnslist_domain
          dnslists = rbl.maps.vix.com:relays.mail-abuse.org
  deny    hosts = *
         !verify = sender
  deny    message = unrouteable address
         !verify = recipient
  accept  domains = +local_domains
  accept  domains = +relay_domains
  accept  hosts = +relay_hosts
  accept  hosts = +auth_relay_hosts
          endpass
          message = authentication required
          authenticated = *
  deny    message = relay not permitted
  accept


#!!# ACL that is used after the DATA command
check_message:
  require verify = header_sender
  deny  message = This message contains malformed MIME ($demime_reason).
                demime = *
                condition = ${if >{$demime_errorlevel}{2}{1}{0}}
  deny  message = This message contains an attachement of a type we do not accept (.$found_extension)
                demime = bat:com:exe:pif:prf:scr:vbs
  deny  message = This message contains a virus or other harmful content ($malware_name)
                demime = *
                malware = *
  warn  message = X-Spam-Score: $spam_score
                spam = nobody:true
  warn  message = X-Spam-Report: $spam_report
                spam = nobody:true
  deny  message = This message scored $spam_score spam points.
                spam = nobody:true
                condition = ${if >{$spam_score_int}{100}{1}{0}}
  accept


#!!# ACL that is used after the VRFY command
check_vrfy:
accept

How can I debug this?
I run spamassassin-2.63 debian packages, self compiled exim-4.24.
I chenged the config not for days and it feels the Problem occurs all
of a sudden, is that a bug triggered by a mail worm? It is happening
more and more often (watching tail -f now).
