My First Impression about Zesle Control Panel

Today I installed Zesle Control Panel on a new VPS. Zesle CP has a free plan with limitation to host maximum 2 domains.

VPS configuration
+--------------------------+
2 cores Intel E5-2690
8 GB RAM
40 GB NVMe SSD
OS: Alma Linux 8 x64
Port 25 is open on the VPS for mails.
+--------------------------+

Installation:
+--------------------------+
Very easy and requires just one command.
It look about 5-6 minutes to complete the installation.
+--------------------------+

Zesle CP License key
+--------------------------+
Took 1-2 minutes to create an account on their website and get a free license key.
+--------------------------+

Add Domain
+--------------------------+
Adding a new domain and installing SSL was just few clicks. It was completed within 2-3 minutes. Creating email accounts on the domain also needed just few clicks.
+--------------------------+

Important Features
+--------------------------+
* Support multiple php versions.
* Inbuilt backup feature
* Inbuilt file manager.
* One click wordpress installation
* etc....
+--------------------------+

Email and Webmail
+--------------------------+
After many attempts and password reset I am still unable to login in webmail.
I always get error message as:
Login failed
+--------------------------+

WordPress mails
+--------------------------+
I don't know why, but my wordpress site was able to send mails to my one gmail account but I never received mails in my second gmail account. I need to dig further to find the reason.
+--------------------------+

Service Status
+--------------------------+
Zesle CP shows many services as down. When I click start button, I get error message as failed to start.

But even though mysql service is listed as down, my wordpress website is working perfectly.
+--------------------------+

The Zesle CP looks cool with great features. But I don't think I will continue using the panel.
