I have DJM Pro, not the AV. I want to block emails with specific attachments in DJM.

Unfortunately, Declude Virus is necessary to properly block attachments (since attachment names/extensions can indicate security risks, whereas they are not yet indicative of spam).


You could try writing a filter to do this, but it could have false positives.

I did write a filter and it appears to be working. Why would a filter that looked for a specific file name give me FPs? The file name is unique so it should not have a match in common language.

If you have a unique name, then you will likely only encounter FPs when people are talking about that file (in which case, it probably isn't a big deal -- if you needed their E-mail, it's because you weren't protected against the virus, but since their E-mail was blocked, you've probably got protection).


The bigger problem is if the filename is something that might appear in legitimate E-mails (for example, if the file is named "yahoo.com", it would block "yahoo.com.url"). A lot depends on how the rule is written.
