How to Manually Test if an SMTP server can Receive Email


Cheap reseller Hosting


Summary:

This document will help in troubleshooting server connectivity and steps to test if MailEnable can send to remote servers. Here are two ways you can manually test if an SMTP server can receive emails:

Using Telnet:

Note: Telnet might not be enabled by default on your system. Consider alternative methods if unavailable.

Steps:

Find the MX Record:

Open a command prompt.

Type nslookup <domain_name>.

Set type to MX: set type=mx

Press Enter

The first record is the primary mail server. Note the hostname.

Connect to the Server:

Type telnet <hostname> 25. Replace <hostname> with the server name from step 1.

Send Commands:

If connected, the server will respond with a welcome message.

Send the following commands, pressing Enter after each:

HELO yourdomain.com: Introduces you.

MAIL FROM: <your_email>: Sets sender address.

RCPT TO: <recipient_email>: Sets recipient address.

DATA: Starts message content.

Type your message body (lines starting with “.” end it).

. (on a new line) to send and quit.

Analyze Responses:

Each command should receive a response code (e.g., 250 for success, 550 for error). Successful connection and message sending will show codes like 220, 250, and 354.

2. Using Online Tools:

Several online tools offer simpler testing:

These tools generally:

  • Allow entering server details and email content.
  • Send a test email and provide delivery reports.
  • Offer additional features like spam score checks.

Choosing the method:

  • Telnet offers more control and troubleshooting details.
  • Online tools are simpler and user-friendly for basic testing.

Additional tips:

  • Remember to replace placeholders like <domain_name>, <your_email>, and <recipient_email> with your actual information.
  • Be aware that some SMTP servers might not allow connections from unknown users or may require authentication.
  • If you encounter errors during the test, research the specific error code for troubleshooting.

How to Convert cPanel to Webuzo


Cheap reseller Hosting


Intro:

This guide will help you to convert your cPanel server to Webuzo. This tool performs many tasks like converting your cPanel server itself uninstalls cPanel, installing Webuzo, and converting all cPanel data to Webuzo. Everything works smoothly and all your users’ websites, domains, databases, emails, FTP accounts, and SSL certificates remain as it is.

Note:  Please ensure you’ve fully backed up your VPS / Server. For the safer side, you need to restore the VPS backup as cPanel will be uninstalled from the server.

Commands

The conversion will monitor the requirements and ask for confirmation. It is advised to type yes and press enter to proceed with the conversion.  

Later, you can check converter logs at:

/root/webuzo_convert/cpanel-webuzo-convert.log

The required time is 5 minutes to 30 minutes based on the resources available on the server and the network connection speed.

Since this takes time, we suggest implementing the above commands using tmux or session, so if your machine disconnects due to an internet connection issue on your desktop the command still runs in the background.  

WHMCS Converter

Webuzo comes with a converter script that helps to convert the WHMCS cPanel hosting accounts to Webuzo. Please refer to the guide.

What Data will be Migrated?

The converter will move the following data:

1) All Domains – Addon, Parked, Sub-domain.
2) MultiPHP preferences per domain
3) All Databases and Database Users
4) FTP Accounts
5) It covers all email-related data like accounts, forwarders, and autoresponders.

6) DNS records
7) SSL Certificates
8) Cron Jobs
9) ACL Packages
10) Users and Resellers with appropriate ownership
11) IP allocation to users and resellers
12) For All plans installed on the cPanel server the same version will be installed on Webuzo.
13) All other data needed for accessing the control panel.


Understand the difference between Converter and Importer?

The converter is responsible for converting the data on the cPanel server itself and doesn’t need a new server. Hence, no IPs are changed. As compared to importer as it does not need to transfer the files across servers. It needs a full backup of the server if in case you need to revert it for restore purposes from the backup.

An importer is required to set up a new server with Webuzo and data is moved from the cPanel server to Webuzo. Further, IPs need to be changed to run the cPanel server compared to cPanel and Webuzo. If you prefer to import the sites instead of in-place converter you can refer to this guide.
