I tried sending a mail to my gmail, and i put a cc my other mail (2 different servers).
In gmail, the mail ends up in SPAM.
In my other mail (my hosted website mail) i get a SMTP error 550 (that HELO thing).

DKIM and SPF are both activated and has passed the check.

Same occurs when i send a mail TO my servers email account. So the problem occurs both ways.

Hello,

Could you let us know the method you are using to send the test email? Are you sending the test email from an email account hosted on your cPanel server, or from another email server that's not using cPanel? Also, you review one of the messages in /var/log/exim_mainlog with a command such as:

Code:
exigrep [email protected] /var/log/exim_mainlog
Thank you.

Hi Michael, thank you very much for your fast reply!

Yes sure, as far as i know, i should send with SMTP - i use webmail for testing purpose to make sure its not the email software that causes the issues.

A) My server uses cPanel / WHM. (The one that im having issues with)
B) My alternative email is hosted at a server that uses cPanel too. I never had any i issues with this mail.
C) My private email Gmail is a normal Gmail account, all DNS are default here, so it cant be the issue.

So i am sending from cPanel to cPanel and Gmail.

I ran the command and i got this (i just copied one mail log instead of all, as it is a long log)

[Moderated Output - Please ensure you remove references to real domain names and email addresses in the log output]

The "funny" thing is that all domains that is running on my server works (still ends up in Gmail spam, but at least they arrive at the other cPanel server) - except from the servers main domain (hostname) - therefore i am suspecting that it could be a DNS issue, but i compared the DNS information with the accounts that works, and it was identical.

Hello,

Could you post the output in CODE tags, ensuring to replace domain names and IP addresses with examples?

Thank you.
