How to install send mail in ubuntu aws

To install and configure Sendmail on Ubuntu on AWS, follow these steps:

Step 1: Install Sendmail

1. Update the package list: sudo apt update
2. Install Sendmail: sudo apt install sendmail

Step 2: Configure Sendmail

1. Edit the Sendmail configuration file: sudo nano /etc/mail/sendmail.cf
2. Add the following lines at the end of the file:

   define(`SMART_HOST', `smtp.gmail.com')
   define(`RELAYHOST', `smtp.gmail.com')

   These lines configure Sendmail to use Gmail's SMTP server as the smart host and relay host.

Step 3: Set up Gmail credentials

1. Create a new file: sudo nano /etc/mail/gmail.conf

   AuthInfo: "U:[email protected] P:your_password"

   Replace [email protected] and your_password with your actual Gmail credentials.

Step 4: Restart Sendmail

1. Restart the Sendmail service: sudo service sendmail restart

Step 5: Test Sendmail

1. Use the telnet command to test Sendmail: telnet localhost 25
2. Type HELO example.com and press Enter.
3. Type MAIL FROM:<[email protected]> and press Enter.
4. Type RCPT TO:<[email protected]> and press Enter.
5. Type DATA and press Enter.
6. Type your email message and press Enter.
7. Type . and press Enter to send the email.

Additional Tips

• Make sure to replace [email protected] and your_password with your actual Gmail credentials.
• If you're using a different email provider, you'll need to update the SMART_HOST and RELAYHOST settings accordingly.
• You may need to configure your AWS instance's security group to allow outgoing traffic on port 25 (SMTP).
• You can also use other email clients like Postfix or Exim instead of Sendmail.

That's it! You should now be able to send emails using Sendmail on your Ubuntu instance on AWS.
