Hey, since some time newly created "copy send to" mails are not delivered anymore. My setup: [INFO] OS version is Debian GNU/Linux 9.13 (stretch) ISPConfig version is 3.2.2 [INFO] php (cli) version is 7.4.15 for Mail I use Dovecot and Postfix I already checked a couple of things and don't get further: I checked database, the entry is there after I put new mailaddress in the send copy to field for user x (DB dbispconfig, table mail_user, column cc) Entries from before (I don't know when it started, a user advised me today), that I find in table "cc" from before, do work as expected newly created entries do not show up in mail-log, the original mail does mails for older mailaddresses do work Can anybody help me on finding the problem? I guess there is something worng with postfix, so that newly created entries are not transported!? I have no clue on how to go on debugging. Thanks in advance!
