    Hello,

    I was wondering if it is possible to have a list of mailaddresses of domains we manage with ispconfig which are dropped or blocked?

    I have a catchall address for @my.domain.tld. When I registered at adobe I used the mailaddress adobe.com@my.domain.tld
    Since Adobe got hacked and lost the emailaddresses are now used for spam and I receive about 2000 mails for that account every day.

    What I do now is a forward for adobe.com@my.domain.tld and forward it to info@adobe.com (They should get the mess they created, not me) but I would like to have it dropped at postfix because there is not such user...

    Is this possible?

    The mails dont get rejected because you accept all emails with a catchall. But you can try to add a postfix blacklist record in ispconfig to reject the emails or you add a transport with the type error to rejct the emails.

    That was exactly what I was looking for... but had to log in as admin :)

    what I do is having a little local php script that I can just call in the browser and add email aliases.

    I used to use catchall domains also and at some point spammers just created fake senders... so I got all the emails back... that's when I just started creating a new email alias for any service I need to supply an email address.

    I don't use catchall on the main domain eg. @domain.tld but only on subdomains @sub.domain.tld and for those I haven't noticed the fake senders...

    For a few clients I do this that they have mail@domain.tld and <catchall>@mail.domain.tld

    Only when websites get hacked fi adobe You get a lot of spam on those emailadresses and they are identifiable because with adobe I used adobe@mail.domain.tld

    What I did before was to create a forward from adobe@mail.domain.tld to info@adobe.com

    They should get the mess they created ;-) but it puts a stress on the server which I rather prevent..
