I'm not saying it isn't a spamc bug but you need an email and you need to run
it with spamc on the command line to replicate the issue outside of postfix.  

Can you do anything like mirror all your mail prior to postfix for a day and
then cross reference to the oops in the log to get an unaltered email?

If the un-truncated message is in the postfix queue it can be exported for
analysis to an rfc-822-format text file using postcat. See
http://www.postfix.org/postcat.1.html

Use -bh for headers and body, envelope metadata should not be needed.

This is the truncated email, correct?  Will it reproduce the issue if
reinjected into your mailstream?

Yes Kevin, the problem with truncation as to give mail to me and from me. 
What's weird, is not cut all the letters

Not sure where to start on this one.  From looking at the code, it's a very
basic function of spamc.

We'll need samples of emails before and after that show the issue.

Also more information at least for me on how your mail flow works.  My
curiosity is something like ClamAV triggering that the email is a virus and
interrupting things.

Have you tried posting about this in a postfix forum?  I will say this is
unlikely to be SA and more likely something in your setup.

Perhaps someone there can assist you in saving the email for analysis.  Without
a pre-injection email the replicates the issue with JUST spamc/spamd from the
command line, there is very little we can do to help.

Sorry, the wording is a little confusing (though much better than I would be
able to write in your native language).

I think you are saying you resolved this and it was not a spamassassin issue?

Play with the postfix I came to the conclusion that SA has become normal to
miss the mail.

master.cf
spamassassin unix - n n - - pipe
< flags=R user=virtual argv=/usr/local/bin/spamc -u virtual -e
/usr/sbin/sendmail -f $sender $recipient
> user=virtual argv=/usr/local/bin/spamc -f -e  /usr/sbin/sendmail -oi -f ${sender} ${recipient}

And it's workerd :-) Strange.

All right. Tomorrow night will gather for all mail in one file. And what
command to feed his spam assassin?
I think the problem for ten years, as shown by google
:-)

Tried on different forums. All cite that this is a bug spamc and sent here. :)
