Emails from server go in spam (gmail, hotmail)

[aitor91]

Hello,
I'm new in this forum. I have the following issue:

all emails sent from my server to a email provider as gmail or Hotmail go in the spam folder. With Yahoo I not have this isssue.

Anyone have an idea of what is the problem?

This problem has come up many times on these forums, most recently within the past severl days, so I'm loathe to go through the steps of discussing it yet again.

In these cases it's possible your IP#, either because your server or a previous server using the same IP# has sent spam to these providers. Or users at these providers have reported emails from your server or IP# as spam even if they weren't.

Usually you can get help from the postmaster websites of the respective providers:

(live.com, hotmail.com, and outlook.com are all the same provider)

You should also make sure you've got proper rDNS settings to match your hostname, that you're not on any public blacklists:

and verify that you've got proper spf and dkim records.

Thanks Jeff for the links. I have taken the test and I'm not in any blacklist. The only test that not is correct is the following:

SMTP Reverse DNS Mismatch: Warning - Reverse DNS does not match SMTP Banner

What is this? Sorry but I'm a beginner.

That's important, and it could email to go into spam folders. It means your server connects under one name (usually your hostname) but your rDNS points your IP# to a different name.
