Hello.
Did you guys got the issue resolved ?
I didn't get this issue, we configured our mails over gsuit. Now I can see normally our all mails landing in inbox but in case of whmcs auto generated mails all of them landing in Spam folder. We checked with rediffmail and in this case it goes to Inbox.
I guess it's the issue with whmcs and gmail. Can anybody help us how to proceed, our IP reputation, blacklists, DKIM, SPF records and PTR records are all ok as of now.
