Hi ISPConfig community, I struggle with a SPAM problem for some time now. I have a "perfect Ubuntu server" with latest ISPConfig 3.1.2. - I activated Graylisting on all mailboxes. - SPAM-Filter is set to Normal mode (it seems to mark a lot of SPAM mails quite well with *** SPAM *** Tags), but not all. - I added some RBL servers to the config through ISPConfig fields, like zen.spamhaus.org - I added some blacklisted mail addresses to the "Postfix global ispconfig settings", and I also added individual rules for some mailboxes, like "if message comes from email@example.com -> discard". I need to forward a lot of "virtual mail addresses" to real mailboxes from domain names like firstname.lastname@example.org or email@example.com to firstname.lastname@example.org. I use ISPConfig to setup the forwarding addresses. Now here I think is a problem. If mail e.g. comes from email@example.com to "virtual address" and then gets forwarded to real mailbox, the rules seem not to work. Even global filters seem not to work and I am not sure about RBL or SPAM-Filter too. Is there something I miss? I get around 30-50 SPAM message all from forwarded addresses right now ... Thanks!
