Hi,

I have add in Exim a
remote_smtp:
driver = smtp
interface =xxxxxxxxxx

Now when i check by all providers google push this directly in spam it say the follow
HELO to IP: fail

[HELO to IP] Your server's HELO string xxxxxx.domain.com is resolved to xxxxx which does not match your server's IP address xxxxx

According to email best practices HELO (or EHLO) string should be sent in the format of a fully qualified domain name (FQDN). In this test we check if your server's HELO string xxxx.domain.com resolves to your server's IP address xxxxx.

How can i fix this i have try a lot of things.
It's a live site so i cannot change something on DNS for this site.
 
Do you have a reverse DNS entry (PTR record) to your servers hostname? As the hostname (and hostname's ip) is used by default for the helo/ehlo to other mailservers.
Even on live sites you change MX and PTR records without issue.

If not, you might want to provide a domain name to check what's wrong.

Why did you do that?
It's best to use spamblockers exim.conf which contains a lot of benefits and adjustments to use on systems.
