Hi there, I´m running ISPConfig latest version on a Debian 12 VPS, hosted by Hetzner. The machine got installed with the howto of the perfect server method. After setup I did a migration, using the ISPConfig migration tool. (Hint @till : Using the migration tool does not migrate old blacklist entries. Bug or feature?) Since there´s a couple of spammers I intentionally blacklisted using the postfix blacklist, I´m currently wondering why the blacklist isn´t working at all: Emails are still accepted from senders which are blacklisted. At least my Thunderbird marks them spam and sorts them to Junk. However: I thought the blacklist will cause any kind of "friendly" hardbounce from postfix, telling the sender "you´re not welcome here". So what I did in ISPConfig is, to put the senders mailaddress to the list of postfix-blacklisted senders. Am I wrong with this? Are there any logfiles I can check why blacklists are not used? Thanks for any hints.
Postfix blacklist works fine here, so there is no general issue with that. Have you double-checked that you used the right from address (check the mail header of the received email to be sure) and that you selected "sender" in the type field?
yes I did. copied the address from thunderbird mail, put it to the field, selected "sender" and hit "save": address is already active at postfix blacklist. maybe my expectations are wrong, whereas the sender will recieve a bounce message from my mailserver?! Are such emails still accepted, but then delivered to the recipient as spam? as mentioned: I expect any kind of bounce message.
