How to mail set 000webhost

Setting up a mail server on 000webhost can be a bit tricky, but I'll guide you through the process.

Note: 000webhost is a free hosting service, and their terms of service may not allow for setting up a mail server. However, I'll provide the steps in case you're willing to take the risk.

Prerequisites:

  1. You have a 000webhost account with a domain name (e.g., example.com).
  2. You have SSH access to your 000webhost account (you can request it from their support team).

Step 1: Create a new user and group

Create a new user and group for your mail server:

sudo useradd -m -s /bin/false mailuser
sudo groupadd mailgroup

Step 2: Create a new directory for the mail server

Create a new directory for your mail server:

sudo mkdir -p /home/mailuser/mail

Step 3: Install Postfix

Install Postfix, a popular mail server software:

sudo apt-get update
sudo apt-get install postfix

Step 4: Configure Postfix

Edit the Postfix configuration file:

sudo nano /etc/postfix/main.cf

Add the following lines to the end of the file:

mydestination = example.com
myhostname = mail.example.com
myorigin = /etc/mailname

Replace example.com with your domain name.

Step 5: Create a new file for the mail server

Create a new file for the mail server:

sudo nano /etc/postfix/virtual

Add the following lines to the file:

@example.com    mailuser

This will allow the mail server to deliver emails to the mailuser mailbox.

Step 6: Restart Postfix

Restart Postfix to apply the changes:

sudo service postfix restart

Step 7: Set up DNS records

You'll need to set up DNS records for your domain to point to your mail server. You can do this by creating the following records:

Step 8: Test your mail server

Use a tool like telnet to test your mail server:

telnet mail.example.com 25

This should connect you to the mail server. You can then send an email using the mail command:

mail -s "Test email" [email protected]
