FuzzyOcr Unexpected error only with MailScanner

[Dominique Marant]

I sent my problem FuzzyOcr in the devel-spam list.
It seems that FuzzyOcr fails because MailScanner truncates emails for 
spamassassin.
How to configure MailScanner for the best compromise ?
Perhaps it would be interresting to create a new variable "Max 
SpamAssassin OCR Size" for size of inserted or attached images ?

What do you think of it ?

Mailscanner truncates emails which exceed a given size specified in
their config. They also truncate inside attachments, leading to "half"
images, which are to be considered as corrupt. jpegtopnm cannot handle
these and will fail. This is not a problem of FuzzyOcr but MailScanner's.


Best regards,


Chris
