Outbound email security can be called as an add-on service that usually comes along with the normal spam filtering or anti-virus services that makes it sure that spam mails, viruses and unauthorized data will not go out of your network through the email servers.
Outbound email security rose to popularity quickly because of many different factors. Some among the major factors why the service is considered important are given below.

Reputation is a factor that affects overall working of any organization. It is found that if a client or prospective customer is receiving a spam mail from your company's email id, the clients may feel reluctant to do business with your company. The email spam filtering service is also of great importance, as it will stop the outflow of unauthorized data.
They can also be helpful in protecting the email server from being misused. Many organizations are facing problems related with hacking and this program can be of great help in facing hacking related issues. However, the genuine emails will not have to face any delays. Most of the top-notch email spam filtering services will ...
... ensure that 100 percent delivery when it comes to genuine mails. You will also receive a notification when the email service is in wrong hands. They can also be helpful in saving the bandwidth.
The working of the software may differ from one another. However, the basic working will be the same. All the emails that are going out will be redirected through the servers of the email spam filtering service provider. These servers will scan the emails for viruses, spam or unknown bulk emails. If any infection is found in a mail, it will be returned to the sender's mailbox. However, the genuine emails will be delivered without any delay.

The implementation of the outbound email security is done by relaying the emails through the servers of the providers. You should have a common knowledge about relaying so that you can understand the process through which the bandwidth can be saved. While sending out multiple emails, if relaying is not done, all the bandwidth will be used. However, relaying will enable the sending by just sending a single mail. This is how the bandwidth is saved.
If you are sending a mail through your email server, it will have to do DNS query in addition to contacting the email servers. If any one of the servers is not reachable at that particular moment, the server will have to queue the email and then try later. SMTP relay service will avoid the above-mentioned issues.

The outbound email security for the email servers will be implemented with the help of two mechanisms namely SPF and SMTP. The email Administrators will make use of the control panel of the provider to enable the outbound SMTP relay service with the help of one of the mechanisms mentioned above. The installation guide offered will help you understand the technique quickly. These major aspects about outbound email security are worth understanding.
