Manual? Well, yeah... I've read it... It isn't that great at covering the key issues to which I refer above.
Frankly, much more could be done.
For example; I just went through the process of getting SPF to work in my email. It's all about DNS, and if one uses a service such as EditDNS, the spf entry must appear as high up the nameserver chain as you can get.
So this is something way beyond the scope of a manual focusing on ISPconfig. Additions must be made on the authoritative nameserver for the domain. For redundancy, it is a bad idea to expect your server running ISPconfig to be the only location of DNS records. (thus, my registrar points to the EditDNS nameservers, and they point to my server)
To troubleshoot such a problem, you have to find and use the services of someone like the espcoalition.org website until you find the real problem and it starts working.
Finding an answer like that needs to be included in a HowTo, not buried down in some forum thread like this!
I don't even expect to go out and buy a book on the subject - it takes way too long to get in print, and the info is so obsolete as to be almost useless.
