Let's say im trying to block a country tld (say .nl or .ru) I tried adding *.nl to postfix blacklist in ISPCONFIG3. somehow the mail still gets delivered. But if i do block an adres like this it works: [email protected] but doing @domain.ru doesnt nor does *@domain.ru anythoughts on this ? Or should i use regex better in this matter ? Thanks ! RObbert
I'm getting a lot of spam from the .science TLD. I tried blacklisting .science in ISPConfig but I am still receiving hundreds per day. This method seems to work with spamdomain.tld but not with just the tld. Any ideas?
Thanks. After playing around with different options I found that science worked (no dot). I tried .science and the regular expression \.science but neither stopped the spam from passing through. I have another (*.download) that is also causing a spam problem. I would like to use the same filter (download) but I wanted to make sure that this only filters the email address and not all the data in the header. The word download is very common and I don't want to discard valid emails. Thanks in advance fro your help. Dave
The postfix blacklist is not a header filter, it is a list of emal addresses, domain names or tld's that the from address is matched against. so the word download matches just against the tld download as the match is right to left.
Thanks Till. This will be handy as the spammers seem to grab a new TLD and fire away. Hundreds per day ... Dave
