IP not blacklisted but email go to spam folder!
My IP address is not listed in any of email spam databases, but when my web app sends email (registration and newsletters) they go to spam folder.
Any clue what's causing this?
Is your web app sending it via PHPMail or SMTP ?
I suspect PHP mail so it will be sent from
If you have the choice change your email from being sent via PHP to SMTP, and you'll find in most cases it wont go straight to SPAM.
is this related to Yahoo by any chance, or are your e-mails end up in spam at gamil, hotmail and others too ?
- Check your DNS health and configuration
- OpenStack billing and control panel for service providers
The IP may be blacklisted internally by the email provider's list even though it may not be on any public blacklist.

I am using hMailServer
It's a J2EE application using SMTP
Emails end up in Yahoo and Gmail spam Folder
There were an incident before: I left the mail server unsecured and one Chinese spammer used it to send tons of spam
Right now the mail server is secured
Most of registred users never come back to activate the registration because of
Reverse DNS is set and there is no DNS issue
Do you have SPF and DKIM/DomainKeys setup? You need to find out if the problem is with your IP or your domain. Try sending email with a different domain or use the same domain on a different IP. You can take the correct actions after that. Let me know if you need further help after that.
Increase email deliverability and know who clicked and opened your emails.
, reliable SMTP service.
