Block incoming emails from specific users

[Adrian]

Hi,

I'm trying to block some senders that everyday send giant emails to some accounts in my AMS.

-------------
Conditions:
I've created this Content Filter Rule, but it's not working:
("Sender" header line contains "xxx@yyy.zzz"
OR "From" header line contains "xxx@yyy.zzz")
AND Email size is larger than xxx KB

Actions:
Reply from ####ADMINEMAIL#### with subject "......"
Delete email
-------------

Any ideas? Thanks a lot.

You should have a match for the SMTP envelope sender also. However, failing that, you can always use the spam filter black list to specify a email address also.

Hi Rob,

What do you mean exactly with "SMTP envelope sender"?
I'm not using the blacklist function because I want emails smaller than a specified size to go through.

Thanks again!

Sorry, I should have been clearer, I was referring to the condition "SMTP Sender Matches", which should be included with your content filter rule. Another option you should consider is creating a new group with a reduced mail size, and moving the required users into that group. Mails exceeding the size will the automatically result in a failure notification to the receipient.

Thanks Rob. I'll update the rule and let you know.
