I have used the HOWTO " Users and Domains with Postfix, Courier,......" to setup my persoanl email server. I didn't have any problems to install the server. After it worked, I installed the command sender_bcc_maps = ..... to make a copy of every outgoing email to an ARCHIVE. (mail account) Finaly I'm now getting double emails of every sent email in my ARCHIVE. After seachring the forum and web, I added the command: receive_override_options = no_addreess_mappings to the master.cf. This had the effect, that I now do not receive any copy of outgoing mail in my archive ? Can anyone help me ? Regards Michael
