I’ve recently recived few mails with broken attachments e.g. zip files with bad CRC, corrupted JPG files etc. It never had happend before so I started my testings to find out what is going on.
My tests showed simple rule: mail scanner is active - test mail with atachment is corrupted. 
I have tested it with few mail accounts and it was 100% reproductive.
I am using Mozilla’s mail cilent.
Has anyone encounter the same problem as mine? Any help?

Could you, please, make the test of ‘before and after’ the corruption (some 20kb long) and send it to me? (kubecj@asw.cz)
thanks,
