Quarantine or blocking email based on sender

Not sure why this is not working.  Please open a support case, because it might be a "feature" added in a recent release, and if so we will all want the problem found and fixed.

In the interim, I guess you will have to block based on IP using DNAT rules.   These are the mailchimp IPs that I have seen recently

148.105.12.0/24
198.2.129.0/24
198.2.130.0/24
198.2.138.0/24
198.2.142.0/24
198.2.183.0/24
198.2.184.0/24
198.2.185.0/24
198.2.190.0/24
205.201.129.0/24
205.201.130.0/24
205.201.134.0/24

Are you referring to my blacklist filter not working?

I am not sure the DNAT will help. Mail comes though a filtering service before getting to the UTM. Any connection directly from a Mailchimp server currently would get rejected by default.

Unless it goes looking through the email header in some way.

I'm certain that there's a suggestion in Ideas for *@*domain.com, but that's not supported at present.  All MailChimp emails include an unsubscribe link, so my tendency is to say that you should let folks take care of any problem themselves.  MailChimp has a strict policy against spam, so if you feel like a particular MailChimp customer is spamming, you might want to bring that to their attention.

Your previous reply left me confused.   

Yes, I was suggesting blocking on IP instead of blocking on sender address.   Yes, that approach will not work because you have a mail filtering service in front of UTM.   However, the mail service should be able to implement a block on IP, Host name / Reverse DNS, or sender name.   Why are you worried about a UTM block if you have a more sophisticated product in front of it?   Or are you just using the UTM block rule for experimentation?   

I do not have control over the filter before the UTM. As I was having problems getting it to block on the blacklist to work, I though I would ask to see if there was something I am missing.

It is not supported because of me using the * twice? 

The emails contain links to attachments that are malicious. As I have got multiple emails from a range of random companies now all coming from Mailchimp. These have been report to Mailchimp but are still getting sent out. 

So I was hoping to reject them all for the next few weeks until they have hopefully fixed the problem.

On UTM, Bob Alfson knows his stuff.   I found this disclaimer when I carefully read the help page for Blacklisted senders:

       "A wildcard does not work in the domain or TLD part of an address."

This is pretty devastating, since you cannot block on host name at all (whether from Reverse DNS or HELO/EHLO), and since it is now clear that you can only block senders based on domain name exact match.  Blocking based on IP address requires DNAT-to-DeadEnd, which is pretty obscure even if you know the IP addresses.   Determining IP addresses is tricky, but their SPF record might help, if an SPF entry exists.

On MailChimp, I am with you.   I blocked them unconditionally at some point in the past, using an email filter that is in front of my UTM.  So far have had no reason to roll back that block.   I use UTM behind the other device and it catches some spam that slips through the other one.   All of my static rules are enforced before UTM, so I have not had to fight your issue.

That is fine then as I can't filter on IP. I will look at getting a list of email domains that are sending from logs and block those.

I will add each one in to blacklist after that with *@domain.com

Thanks for pointing that out.

Here is a list of the 548 MCDLV.NET sender domains that I have seen in a recent 90-day period.   The size of the list is discouraging, given your constraints.
