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 [email protected] 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 [email protected] and forward it to [email protected] (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.
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 [email protected] 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 [email protected] What I did before was to create a forward from [email protected] to [email protected] They should get the mess they created ;-) but it puts a stress on the server which I rather prevent..
