How Emails and SMTP Works in Cyber Panel & OLS?


Recently I Created a Digital Ocean Droplet > Installed Cyber Panel + OLS Using SSH.

Created a Website Under Cyber Panel

Created Email ID for that Site Under Cyber Panel

Now Able to Send Emails From Rainloop Web Email Provided by Cyber Panel.

Created DKIM + SPF in Digital Ocean Domain Settings ( Copied Records from Cyber Panel )

After Records Created in Digital Ocean, I send some Mails from Rainloop.

All That Emails Verified and Signed.

The receiver Can See, Mailed by and Signed by Details.

Till, This everything is fine ( I think ).



Now, The Problem.

I wish to send emails from my website.

So, there I need a few things.

1 - SMTP Host

2 - Port

3 - User ID

4 - Password

I know User ID and Password, which I'm using to Login in Rainloop.

Port mostly 465 and 587 ( I saw this in SSH, once OLS Installation Finished )

But, SMTP Host....

When I checked Records under DNS, I could see " "

most f the situation, that's correct.

that should be correct, because from there only I took DKIM and SPF, they worked good.


I added in Digital Ocean as A records.


goto my web application.

and put these settings


Port - 465

User Name - [email protected]

password - secret password


But, My web App saying - Unable to connect to host.

What I missed to do? should be created in Digital Ocean as A Record or TXT?

or as CNAME?

Only I have confusion on this...

Maybe the error is something else.

I have described almost everything I know...

kindly help me to sort out the issue...
