As my ISPConfig 2 setup has stopped working, until I get a replacement in place, I need to maintain the system by hand-editing config files. Most of this is OK, but I'm not clear where the aliases for forwarding email to other addresses is set. It is a perfect setup on Debian running Postfix. For example, if a an email address email@example.com is set up on the system and in ISPConfig it was set to forward email to "firstname.lastname@example.org" where is that stored in a configuration file? I can find the detail of where it should go in isp_isp_user / user_emailweiterleitung but I don't know what config file that table updates. It would be really useful if there was a list of all the files that ISPConfig 2 updates, but the email forwarding is the one I'm puzzled by at present.
