I'm just try to intall mailcow, installation running well.But i have issue when send email to gmail, yahoo and outlook.
Email goind to SPAM.
Please kindly help me for this.
Have you check your IPs sender reputation?
Are you on any DNS blacklists.
Do you have a SPF record?
I found my linode IP on blacklists with hotmail, I verified my IP with Microsoft's postmaster tools and get unblocked straight away.
You need to open the email header of the message that was sent to SPAM as this will explain why.
you can try this quick test to see if you have spf/dkin etc set correct: https://www.mail-tester.com/
DNS blacklist no,SPF have.
How to check blacklist on hotmail/outlook?
Can i share the header?
Mailtester result 10/10.
Take a look here https://mail.live.com/mail/postmaster.aspx
Do you have an IPv6 address on your server? If so make sure it's in your SPF and has a forward and reverse IP.
Fire away... It might help seeing the IPs so we confirm the DNS records.
I agree, it the only way we can give a definitive answer, otherwise we will just be guessing at what it may be.
Here the header
Well all looks good here, the only thing that I can imagine is your TLD is a .xyz.....
Not sure other then marking it as not spam in gmail what you can do here? sorry!
