Can't select secondary MX in Email Routing
web.mydomain.tld is my full ISPConfig3 install with a satellite, ns2.mydomain.tld, as backup MX and DNS, it's a mirror of web.mydomain.tld. When I try to add an email transport I cannot select the satellite (ns2.mydomain.tld) as server , only web.mydomain.tld, this makes it impossible to setup a working backup MX as any routing would lead to a bounce with the error: mail for web.mydomain.tld loops back to myself.
If I "hack" the database and change server_id from 1 to 2 in mail_transport my backup MX starts working like expected, that is all it takes. Please let me know if I can give you any further information.
