Be sure to read the docs above. Alternative configurations (Not yet done) Some ISPs / providers have different kinds of users underneath the same domain, e.g. allows IMAP only for users who pay more. Another case is when a provider requires different configurations depending on situation: E.g. one only works within their ISP network, others only work in their hotspots etc.pp.. In these cases, we'll create one file for each config alternative, with filename domain, space, reason, e.g. "gmx.de" and "gmx.de pay". Because TB3 does not requests domains with a space, these alternative configs are effectively inactive. This problem would of course be much easier with a database. Ben Bucksch
