How can I customize email headers ?
I want to hide "X-AntiAbuse", "X-Source", "X-Source-Args", "X-Source-Dir" headers. How can I do that ?
sounds like a job for a plugin, possibly via the message_headers_output hook Plugin_Hooks ? Roundcube Webmail (http://trac.roundcube.net/wiki/Plugin_Hooks#message_headers_output)
