How to Track an SMTP Server

smtpDid you know that so many things happen behind the stage if you send emails to an organization?  Immediately you send the mail by clicking the send button; it is forwarded to the simple mail transport protocol service provider. The SMTP service provider gets in touch with the recipient mail server, and they transfer the message in your mail to the mail server which you can buy at http://spammer.ro, for example.

However, the following reasons might hinder the mail server from sending emails.

  1. Loss of internet connection by the mail server.
  2. Cheap disk space, which eventually causes the operating system to hang or even crash at times.
  3. If the mail administrator makes some configuration errors, which confuses the SMTP service to be confused on how to send mails.
  4. If the mail server is added to a blacklist, which prevents it from sending emails to recipient servers, by referring the blacklist as a means of eliminating spam.

In every organization or business, outgoing emails are valuable and plays a vital in communication with external or internal partners.  Therefore, every organization or company should lay some means of monitoring the SMTP server.  However, the monitoring service is also available in websites offering control support. Nevertheless, the tracking procedure is similar, here is how it works.

The tracking service provider website or SMTP tester tries to establish a socket link with the SMTP server, through the use of transmission control protocol (TCP).  The whole process includes broadcasting an SYN packet to the SMTP server, as you expect an ACK packet to be the reply.

After the website receives the ACK packet and a successful socket connection being established, the tracking service site will create trial communications, through the use of protocol commands.  The means is functional, and as a mail sender in an organization, you easily evaluate it using the common terminal program telnet.

If when assessing a link will be started, the SMTP server will reply you are using its banner, which indicates “related to mail. The domain name. Net.” If you will not receive any banner automatically, that indicates something is not okay.

If the link is established and you receive a banner from the SMTP server, it will make a formal announcement to you, just like a mail user, by sending a hello command, which is then followed by the domain source of the mail. For example, you will receive a command which says; “Hello my. Domain name.net.”

If the connection is in order and everything okay, the response from the SMTP server will be “Hello my.domainname. net is happy to meet you”.

At such stages, it is clear that the SMTP server is completing connecting requests, and it will respond to any command you make.  However, if the tracking service indicates failure at any point, it is capable of logging the time the crash happened, the failure and any content received by the failure, which will be useful in determining the problem.  The tracking service support will then inform you through an email, an SMS text or even by making phone calls.  Nevertheless, some monitoring service providers allow you to test their method before using their service.
