Mail to Gmail Accounts Goes To Spam Folder
My business has two domains. I can send email to a Gmail account holder using the primary domain with no issues. But amy emails from what I call the "secondary" domain below are treated as spam. This occurs with two different email addresses using the secondary domain.
Both domains are hosted with Bluehost. Exhaustive research has revealed the following:
- Settings in Thunderbird are exactly the same, e.g. ports, security, SSL/TLS, etc. for each domain.
- There is no subject line or content that could possibly be regarded as spam.
- MXToolbox indicates that the secondary domain is not on any blacklist.
- Extended support via Bluehost reveals that SPF, DKIM, and DMARC records are all correct.
- Email sent to a Gmail account using the CPanel (Roundcube) is not flagged as spam. Only emails sent via Thunderbird are flagged.
- Emails sent to a Gmail account from the secondary domain using my mobile phone, but still on the same network/IP address, are not flagged as spam.
- If I first send an email to one of the secondary domain emails FROM Gmail, then reply to it, the reply is not flagged as spam.
After many hours of head scratching (and later, head banging), I am pretty much at my wit's end with this problem. I'm an electronic engineer but this one is definitely out of my wheelhouse. Any help would most certainly be appreciated!
Thanks in advance, Don

It may help to post screenshot of server settings pane and SMTP server settings pane for that account. That would provide some possible ideas. thank you
My apologies for the long delay, we had a death in the family.
Here are the requested images. Note that all settings except the actual domain name are exactly the same between the "primary" email account (whose mail is not marked as spam by the Gmail servers) and the "secondary" email account below, whose email is treated as spam when received by a Gmail recipient.
Thanks, Don
Are you using a sig on the email? Fancy sigs can trigger being flagged as spam.
Hi David,
No sir, no sig at all.
Thanks again, Don
All I can think of that there is an error somewhere in bluehost's settings. BUT, I will also see if I can get a super guru to look at this. There are a few, if I can free one up.
Thank you very much, David, I appreciate the help. It's certainly a mystery to me.

Look at a sent message also. Sometimes antivirus products insert advertisements in sigs. Just a thought...
No advertising is being inserted. But in tinkering, I've noticed something else very bizarre.
If I send a message from the secondary domain only to a Gmail account, it gets flagged as spam. But for some unknown reason, if I also cc: another non-Gmail account, the message properly gets to the Gmail user's inbox!
I have not 100% verified this behavior, but have observed it on at least three (3) different emails I've sent. Very strange behavior...
I am lost. I do have a fear of web-hosted email. I have used them and performance is never completely reliable. But I am prejudiced. Maybe someone can see through this. My hunch is bluehost, but I have no good reason for that.
I sincerely appreciate your efforts to help, David. This one is definitely beyond me as well - I was floored when a simple cc: to someone else made the email land in the proper location.
Thanks again and take care.
Don
we didn't have this problem with typewriters...
No kidding! I can still hear the bell ring to shove the platen back to the other side...
