Strange situation

[Luis Marcelo Achite]

Hi,
I have mailscanner configured with spamassassin and two anti-virus 
software. Some messages arriving are being classified as spam, but the 
strange part is the subject is changed for something like "{Spam not 
delivered}{Spam not delivered}{Spam not delivered}..." for several 
lines. Looks like that there is a loop cycle. Anybody from the group 
know why this is happening.
Thanks for any info regard this problem.
Marcelo
