Hello I have created a new server following the steps in the manual "The Perfect Server - Debian 10 (Buster) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.1" Everything works fine, except when adding new mailboxes where I receive the error " The -Send outgoing copy to- field does not contain a valid email address" I do not receive this error on my other servers. and I'm not covering the send outgoing field. I've rechecked the settings but I don't see where the problem may be. I hope you can help me. thank you
You seem to have an ISPConfig 3.1dev version installed which has an issue that has been fixed last week. Please run ispconfig_update.sh command and choose 'git-stable' as update source.
