Send Mail From Linux Command Line Smtp Server

Send Mail From Linux Command Line Smtp Server – While you are trying to configure your mail servers, you may want to check that your MX records are set up correctly. This article will show you how to perform an MX lookup using the command line interface.

An MX record is an entry defined in a DNS zone configuration that specifies which mail server is responsible for handling a domain’s email. For this you should configure at least one MX record to receive email for your domain.

Additionally, you can add many MX records, where each record must point to a different mail server. It serves to balance the load of your email infrastructure. However, it is still fine to have only one mail server.

The last right column of the results is the MX record you are looking for. Specifically, these are email servers.

The utility is available by default on most platforms: Windows, Unix, Linux, BSD, Mac, so you don’t need to install it.

Enter the command in the terminal, if it is available you can use it. Otherwise, if you’re using Linux/Unix/BSD, you can install using a distro-based install command.

See a lot of details. However, you can filter to print only what we need. here is

A Sysadmin’s Guide To Configuring An Email Server

Finding the MX is a simple task and should be well done if you are responsible for mail server configuration or DevOps.

If you know of any other method to find MX, please share it with me in the comments. I’d like to know !Sometimes you may need or want to send an email from the command line. You can generate a report from a database or your application and want to send the generated report via email. Assuming the report is created manually via scipt and called using crontab.

In this tutorial we will learn how to install MSMTP and Mutt. We will use MSMTP to forward email to Gmail. If you want to follow this guide with a Gmail email account, please create a new email address to use on your server and do not use your current Gmail account. One of the reasons is that your Gmail account password will be stored in plain text by default. You can use pgp to store your password securely. Another reason is that the account you will be using to send email from the server may be locked due to a different location between you and the server.

If you’re having trouble signing into Gmail from the server, you may want to follow the steps listed on Google’s support page.

We can use MSMTP to send emails, but unfortunately we can’t include attachments, so we’ll use Mutt to help us send emails with attachments from the command line. We will be using Ubuntu 14.04 for this guide, but any Ubuntu release and even Debian release should follow this guide.

Before we install MSMTP and Mutt, we will update our server to the latest update. If you are installing MSMTP and Mutt on an existing server, make sure you can update the server to the latest release.

To connect to an email server using SSL/TLS, we need a file containing Certificate Authority (CA) certificates. You can check whether your server already has the ca-certificate package installed or not using the command below:

If the ca-certificate package is already installed, you will get an output similar to the above output similar to the above output. If you get a blank output, that means

Email Client With Browser Capabilities

The package is not installed and you need to install it. You can install this package by running this command:

Create an MSMTP configuration in /etc/msmtprc with the following content. You will need to enter your Gmail username and password in this file.

. If you use a different name, make sure you set the account you want to use as the default.

Mutt installs Postfix as one of its dependencies. You will need to select the package configuration manually. You can choose No configuration.

Now for the fun part. Sending email using msmtp is very easy. The easiest syntax you can use is:

The above command will send an email without subject and body / content “Hello, this is sending email via msmtp”. To send an email with a subject, you can use this command:

The above command will send an email with a subject but no email body or body. What about the entire email? you can use below command:

Of course, you don’t need to put email directly in the command line. Another way to create an entire email like we did earlier is to create the content file below. Enter the name of the email.txt file

How To Send Mail On Linux

So far you have learned how to send email using msmtp, now we will use mutt to send email with attachment. You might be wondering why we need both msmtp and mutt? The answer is that msmtp is a mail transfer agent (MTA) and can only send emails, but not create attachments. Creating email as MIME is more of a mail user agent (MUA) function, so we use Mutt in this tutorial.

We will install logwatch to generate reports to attach to our sample. Logwatch actually has options that can send a report directly to email. We only use the log trace report as an example in this tutorial.

The owner of the file may be root. We will change the ownership so that our current user is the owner

The command above will send an email with an attachment but an empty body because we placed the content from

. To send an entire email with a subject, recipient, and body, create a file that contains the message you want to put in the body of the email. Then you can change

With the file name. For example, if you put the email body in the email message.txt file, you can use the command below:

In this tutorial, we learned how to send email from the command line using MSMTP and Mutt. We learned how to send emails with and without attachments.

Sendmail is a very simple and straightforward MTA (Mail Transfer Agent) that implements SMTP (Simple Mail Transfer Protocol) among other things and can be used to transfer email, usually even on the cheapest KVM VPS running Linux. Although a commercial version called “Sendmail” is available, the sendmail discussed in this how-to article is the UNIX-based version that comes with almost every Linux distribution, as well as *BSD (FreeBSD, OpenBSD, and versions). Using the sendmail command is perhaps the easiest way to send email through the Linux CLI (Command Line Interface), except for mailx, which can be used in conjunction with sendmail to make sending and receiving email from the command line even easier. As the name suggests, sendmail can only send email and does not store received email in POP or IMAP mailboxes.

The first interesting piece of information you might need to test sendmail is the path to the binary file that is executed when we issue the sendmail command on the command line. To find this out, we will use the which command as shown below:

The output above means that the full path to the binary file of our sendmail command is /usr/sbin/sendmail, which you need to remember for the steps below.

If you want to customize the sendmail configuration files, you can usually find them in the /etc/mail/ directory on UNIX (FreeBSD, OpenBSD) and Linux (CentOS, Fedora, Debian, Ubuntu) systems. The main sendmail configuration file is /etc/mail/sendmail.cf, but customizing this is not part of this tutorial. A good place for more information is the sendmail man page, which you can view by running the man sendmail command. Now let’s get to the interesting part of this sendmail command line tutorial.

If you want to quickly test whether the sendmail command is working correctly and then use it, for example, in shell scripts, via the command line or even from PHP scripts (PHP supports sendmail for sending emails from PHP scripts – you can set the sendmail path in the php . ini), you can issue the command below on UNIX or Linux:

[email protected] is obviously the email address you want to send the test email to. This sendmail command line example will send an empty email with the subject “sendmail test” to [email protected] if the test succeeds. You can also send longer emails that include a subject, body, and extra headers if you want, but it’s usually not necessary just to make sure sendmail works. However, you can do this by:

1.) Create a file called mail.txt (or whatever you want) in ~/mail.txt with vim or nano or your preferred text editor

2.) Paste the following content into
