FuzzyOcr Unexpected error only with MailScanner

[Kash, Howard (Civ, ARL/CISD)]

Versions 4.56 and 4.57 (beta) have changes to address this.  4.56 extends the "Max SpamAssasin Size" option, and 4.57 adds a new "Max Spam Check Size" option.  See MailScanner.conf for details.

Beware, there is a bug in the 4.57 version that causes it to not properly detect silent viruses if you have "Max Spam Check Size" set too low.  As far as I know, it hasn't been fixed yet.  It properly stops the virus, but sends a striped message to the recipient anyway.

Subject: FuzzyOcr Unexpected error only with MailScanner


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

An other reply :
---------------------------------------


	looks like Mailscanner is the issue (according to decoder's mail). Amavis 
	works perfect, maybe you could consider it.
