Comments on How to Block Email from certain TLDs (Top Level Domains) in ISPConfig
Spam is an annoyance and there's a multitude of ways to counteract it. However spammers also get smarter and try to bypass filters and stuff. In addition, ICANN has lately approved a great mean gTLDs (generic Top Level Domains), like .biz, .info etc. Some of those gTLDs are, in my opinion, exclusive used by spammers. Lately, I have gotten a lot of spam from the .xyz gTLD. So the question was, how to block email coming from such domains using that gTLD.

Danke für die Anregung. Bei mir hat folgendes sehr gut funktioniert. Thanks for the suggestion. For me this has worked very well. "BOUNCE_PREFIX"
Is it possible in the ISPConfig blocking outgoing mail to TLDs domain? In order to block spam for example.
it should be:
/<.+?@+?spamdomain\.xyz>/it filters both "[email protected]" and "[email protected]",
on the contrary, any spammer subdomain would bypass the filter.
@MaxT Not sure how old this thread is but it should actually be something like this:
/@.*\.xyz$/
this will filter out only email addresses and not text located in the subject that could possable be a false positive.
Here's an example --> https://regex101.com/r/2a7vCF/1
Surely in order to block subdomains of a domain, along with the domain itself, shouldn't the regex contain an OR condition like so...
<.+?(@|@.*\.)spamdomain\.com>
this should block the following;
[email protected] & [email protected]
But shouldn't block something like [email protected] which is obviously a completely different domain name
