The netizens are often bitten and bugged by 'spam messages', unauthorized emails and email worms. They get into the system and impede the process of mail delivery. The SMTP servers need to build up a strong line of defense to frustrate the infiltration of this nagging problem into your system. The solution is using the SMTP proxies. The main objective of using these servers is to make the mail servers be more active and efficient while handling email delivery. The proxy servers provide much-desired protection against the harmful worms that may corrupt your net system.

This SMTP proxy itself acts as a server between the email sender and recipient. It blocks the unwanted messages with help of multiple effective ways such as load balancing, filtering etc. Of several advantages offered by this server, the most important is providing connection management. This is done by putting an upper limit to the number of connection provided to the clients. The general rule is a client can have an access to only one connection which implies that only one message can be sent at a time. Such a rule has been applied to thwart the ...
... threat of the denial-of-service or DoS. A virus, enable of creating DoS problem, uses all the connection resources of a server. As a result, the clients are unable to have an access to that particular server. The SMTP proxy server solves this problem by restricting the number of connection.

Another important service that these proxy servers provide is bandwidth throttling. This is a clever technique to put an end to the invasion of the spam messages. The spammers generally send bulk of messages at a time. This may lead to server crash. To overcome this problem, the SMTP servers ( of course the proxy ones) limit the flow of traffic at a time. Due to this restriction, the legitimate senders wait untill they are able to send email again while the spammers abandon their effort. Load balancing is another vital service on offer by the SMTP server of proxy type. In today's world, where correspondence via net has become so much popular and essential too, one email server is not enough to manage the enormous emails exchanged day in and day out. The proxy server makes a logical division and creates multiple servers that handle the limited load assigned to them.

The SMTP proxy servers provide another interesting and important service - interoperability. With this feature, you are able to change the mail servers while still being attached to the same proxy server. What happens in this case that the internet service providers change their incoming and outgoing mail servers in response to your change but does not interfere with the proxy server. An SMTP mail server came into being to deal with the mail delivery. But with the passage of time, the spam attack has become a serious threat for the emails senders. They often encounter the 'spam' problem. So, a strong need was felt to filter out the spam messages. An effective way to sort out this problem is definitely using the SMTP proxies.
