Hi, Sorry, if this has been answered already and I didn‘t find it. I have a single mailbox, which should receive mails and send a copy using the mailbox owner‘s mail address as sender to an external mail address. So, it should not keep the original sender, but do a forward like it would happen on a client. Can I configure a filter for this or is there an option in ispconfig? The „send copy as“ and forward keep the original sender. Thanks a lot for your help!
