I am using standard SA which comes with CentOS 5.
The name of the rpm kit: spamassassin-3.2.5-1.el5.
I just installed last Thursday with "yum install spamassassin"
Zero customization for the time being.

The "tcpdump -i lo -A -s0 port 783" command gave me the following
information:
For a test e-mail with length 240 bytes the content-length field had a
value of 247.

That was a clue where to search further and with simple code reading I
quickly found the bug.
It is really possible that the message size value was incorrect since
long time but seemingly
no any extension was dependent on the precise value till spamd came into
the picture.

With that fix in mg now the spamd is in production at my site
(for my own e-mail address only for the time being)
and it has happily assassinated many spam e-mails already.
