Need help from gmail users. Emails kicking back with 535 and 550 error messages. Support can't solve.
Not all, but a few emails I send from my inmotion hosted domain randomly come back with 535 incorrect authentication and 550 high probability of spam errors. These are one-to-one emails with no suspicious text or links. Some are even part of threads in progress. Makes no sense as all authentication settings in gmail are correct (double confirmed with inmotion). I have been submitting tickets for 3 or 4 months and get a variety of answers, NONE of which have solved the issue.
I have been trying to reply to an email a client of mine sent me and I keep getting a 550-Spam-message. The message is simple and I tried making it more personal the second time and still got the message. I would like to know why this specific message is being blocked when it is clearly not Spam?
