SendMail is a simple and easy MTA (Mail Transfer Agent), which uses SMTP (Simple Mail Transfer Protocol) among others and can be used to send email, often even on the cheapest KVM VPS running Linux. While there is a commercial version available called “sendmail”, the email we’re talking about in this article is the UNIX-based version that comes with every Linux distribution including *BSD (including FreeBSD, OpenBSD and variants). is ). Using the send email command may be the easiest way to send e-mail through the Linux Shell CLI (Command Line Interface) other than Mailex, which can be used in conjunction with sendmail to make sending and receiving text in the command line easier. . . As the name already suggests, SendMail itself only sends emails and does not store received ones in POP or IMAP mailboxes.
The first detail we will need to test sendmail is the path to the binary file that is processed if we issue the sendmail command on our command line. To check that, we will use the command shown below:

A good source for more information is sendmail’s manual page, which you can view by running the man command sendmail. Now to the interesting part of this sendmail command line.

[email protected] is the actual e-mail address you want to send e-mail to. If the test is successful, this example sendmail script will send a free email to [email protected] with the subject “sendmail test”.
