Add server setting from providers unknown to K9Mail

[Johannes Dreher]

K9Mail knows the settings (IMAP, SMTP,...) of the major e-mail providers. However, for small providers users have to look up the settings and manually enter them in K9Mail.
Is there any database where users can add server information of providers unknown to K9Mail?
This would especially help users who have no idea about server settings at all to easily use K9Mail.
