Hello,

I got several errors, and no information/ hints on what is coud be wrong in source code documentation.

I could install required modules, and got empty tables in database, but adding when I tried to add a server, I got mail above, or something like no password specified and then after "create password" module is not configured to change password. I did not find a place to put a password, Further no hint, what to fill in the field domain-name, when first configuring Imap (ok thats Imap moduel) but anyhow, they are linked (at least from webmailplus to Imap, so why not back?). Anyhow its level of documentation is quite poor in comparison to other modules. I tried also under user-settings to put user and passwore of my google account, anyhow, documentation links dont work, please help!
