Hi, we moved over to our new ISPconfig-based mailserver on saturday and (most) things are working fine. I just noticed i got the same mail twice: * in INBOX marked with a [SPAM] header * in the Junk folder The checkbox for sorting Junk is on. I checked the postfix and message ID in the header, it's twice the same mail to the same target email. Any idea where to search for the config error that (i presume) is causing that?
