"{Blocked Content} Warning: E-mail error detected" with no particular reason!

[Idan Plotnik]

Hi,


You right, BUT:
1. I didn't send an attachment!
2. I know this but I put "0" in the "Check Attachment size" that the
MailScanner will not check attachments.

Do you have another idea ?

Thanks a lot.

Here is a hint:

-From your logs :

333 >

-From the generated messages

At Tue May 25 12:17:05 2004 the virus scanner said:
    MailScanner: Attachment is too large


You must know that the max size setting is in bytes, not in megs.
