MyBB Community Forums

As the title says, I am trying to send a mass message via email from my forums to all my admins.
MyBB tells me that the email been delivered. How ever, no one that is supposed to get the email gets it.

My email settings:


I did try to contact my host, and they told me the settings were correct we I should go here for support.

do the other mails deliver to mail inbox ? does system mail log show any errors ?

forum admin panel >> tools & maintenance >> System Mail Log

Proof email is being sent:





And email logs:
The mail server does not understand the MAIL FROM command. Reason: 550 From address must match authenticated address

^ how about log entries at System Mail Log ?

I did notice I did post the wrong logs, I did update my post with the new logs. Will post one here aswell:

The mail server does not understand the MAIL FROM command. Reason: 550 From address must match authenticated address

And when reading the log I understand whats wrong, rip. Problem Solved.
