Ok, getting there step by step ;-). FYI still no response from Google on my support request :-(.
Retested and found som news:
The autoforward works for mails sent from non-Gmail accounts. These Emails are delivered to the local mailbox at heliohost, forwarded to Gmail AND received/accepted in my Google mailbox. 🙂 🙂 🙂
BUT for mails sent from Gmail accounts (I've tried a couple) autoforward mails are not yet accepted by google. Emails are delivered to the local mailbox at heliohost but NOT received/accepted by Gmail
I'll use this new/current toolbox results and current setting to add to my support request at Google and hope for some response now.
Running the Google toolbox again for the domain stamphaus.nl I see almost everything is 'green'. Also the MX-records and MX-search check is approved/green.
Only two 'yellows' remain (of which the second one is NOT A PROBLEM according tot Google):
DKIM is not configured .... strange, this issue is not showing up in your list...? There's no additional information with that score in my overview...
No Mail exchangers ... that's no problem / caused by the auto forward. (the additional information in that line states that I can ignore that).
