Firm Gmail, i.e. Google Apps -email, with K9 -email program? I am struggling with this kind of Google Apps -site, example from Google.com -site here.
  
  


I use two email-clients in Android: default Gmail -client (because it is tied to my Gmail) and K9. I am able to set up all Gmails to K9 but one email i.e. the firm email from the site https://www.google.com/a/firm.com (excluding ofc the Android-tied-gmail -account, more here). It means that I am using K9 and default Gmail-Android -program but I would like to have all emails under K9. Is it possible and how can do it here in the case of the Gmails targeted to firms? I think such gmails are called something like Google App or something like that, not sure. 

The firm Gmail is not accepted like this in K9:


  Username: forname.surname
  
  Password: correct
  
  IMAP server: mail.myFirm.com
  
  Security type: SSL (always)
  
  Port: 993
  
  Use compression on network: Mobile Wi-Fi Other


If I change the IMAP -server to mail.gmail.com, it gets accepted but it won't work correctly -- redirection problem. But now I am stucked why it does not accept the above settings?!

Perhaps useful to other like-minded


  
  All emails under K9 -app?
  Email-client with Sent emails from many emails under IMAP?
  Setting up IMAP over device-swarm that has a Debian Desktop -client, more here.
The default settings by K9 have at least two mistakes:


  
  use imap.gmail.com instead of mail.gmail.com.
  use full emails for usernames such as forname.surname@myFirm.com, not just forname.surname.
  


Example settings
