Set Spam filter to block emails from subdomains

[MacWeb]

Hi,

I need to block emails from sender email in a subdomain.

I already try to add *.domain.com on Block mail from an entire domain: but I get an error.

Will subdomains be blocked if we just add domain.com ?

Thanks in advance

Hello,


Do you want to block all incoming emails from sub-domains of domain.com, or what?

but I get an error.

What does it say about? And where do you get it from?

Hi Alex,

I need to block all emails that come from any subdomain of that domain.

When I try to add email filter in "Block mail from an entire domain:" DA return me this error:

Details:
Invalid domain

Thanks in advance,

Anthony

OK, and where exactly do you add it?

How is the domain written there? Is it an internationalized domain or not?

Make sure, you've got no white spaces or tabs after and before.

Sorry Alex

Where:
In DA>Email management>Spam Filters "Block mail from an entire domain:"

in "Block mail from an entire domain:" i fill with *.domain_name.com

I fill the real domain name and I get domain is invalid.

Thanks in advance

In this case you'd better use SpamAssassin. Or add domainname.com

If you have admin access to the server, then blocking is better done in SpamBlocker; then the server doesn't waste time processing emails at all; it just refuses to accept the email based on the subdomain name.

But the way it's written you need to block each subdomain separately.

Yes, if you've root access into your server, then you might want to add your *.domain.com

in /etc/virtual/blacklist_domains

Note, I didn't test it myself, but ii I understand this http://www.exim.org/exim-html-current/doc/html/spec_html/ch10.html correct, then it should work. But in this case this blocking will apply for all email accounts hosted on the server.

Thank for all your help

Just one more question, adding just domain.com in DA will block the domain emails and also subdomain emails ?

I will also try *.domain.com in /etc/virtual/blacklist_domains

Thanks in advance

Yes, for any mention of domain.com in from, as it adds this line into filter:

or $header_from: contains "domain.com"

Thanks for all your help

Now I understand how that filter works.

I didn´t find any guide explaining DA panel in detail.

I am happy to find helpful people in this forum.

Thanks a lot

Sorry but this doesn't look correct to me.

@MacWeb: are you referring to the Mail Filter in DirectAdmin control panel, or are you referring to the /etc/virtual/blacklist_domains file?

If the latter, it has nothing to do with filters. I'm not sure if it works the same way or not (and I wrote it); you should test it.

Sorry, my mistake. Jeff is right, my answer in POST #10 refers to the Mail Filter in DirectAdmin control panel only.
