Emails with random letters

[toolshed1]

Hello,

Is there a way for me to block emails that contain random letters? For example: affasdffsdfdada

No particular pattern just random letters.

Thanks.

Hey toolshed,

That would be quite difficult to be honest - as random letters could cause potential word blocking in general.

I would definitely venture to find some more details within the email that could be used - random letters would be exceedingly hard.

The most viable option though if you're seeing a lot of emails like this ; would be to contact Cisco TAC with some samples so we can have the spam team have a look and perhaps it could be stopped as it is spam.

Thanks,

Mathew

Mathew,

That's exactly what i did. I submitted samples to TAC.
