I would like to solve this long running issue. You can see previous posts on this topic below.
I have an old email address which I forward to my new email address, on the same Virtualmin run mail server.
I get a LOT of spam in my new email inbox. They are all sent to my old email.
I believe they are not being checked for spam, or being on a blacklist at least, due to them being a forwarder. Most of the senders I check are on blacklists like Spamhaus.
I have set Postfix to check Spamhaus and a few others, but it does not seem to work unless its emailed to my new email account direct.
I also setup a spamassassin local.cf file with rules to check spam databases, but that seems to be ignored also, as per one of the old threads I list below.
There are spamassassin header scores, so spamassassin must be doing something, but its not checking these blacklists, and so the score is not high enough. It doesn’t seem to use local.cf.
So perhaps the issue is, Postfix not checking forwarded emails, and spamassassin not using local.cf on forwarded emails?
So how can I spam filter these forwarded emails for spam, seen as they are on blacklists?
It is my opinion all email arriving into the server should be checked regardless of it being forwarded or not.
Also, the forwarder has been tried from the user settings in Virtualmin, and then the user doing it within Usermin, so both dont work.
