Postini Anti-Spam Filtering Benefits

• Shield your MX record

Every domain has at least one mail exchange record (MX record) to relay emails to the correct address. If your mail server has only one MX record, it is exposed to the public for spammers to easily view and access. Inevitably, junk mail, viruses, and harmful messages will flood your unprotected mail server. 

With Postini Email Security, your mail server will be sheltered from the outside world by up to four MX records provided to you upon setup of your Postini^® service. No messages will reach your system without first routing through this anti-spam and anti-virus filter. Your server and MX record will be safe from infiltration and protected from malicious or junk emails.

• Protect the repution of your mail server 

If your MX record is not sheltered from public view, spammers can “borrow” your mail server and use it to send mass spam all over the Internet. Your server may then be placed on an email blacklist which would cause other domains, potentially those of your clients, to reject mail sent from your MX record. With Postini Email Security, your mail server will be sheltered from the outside world by up to four MX records provided to you upon setup of your Postini^® service.

• Block unsafe emails

Unwanted emails waste your resources and are potentially dangerous. Spam may redirect you to phishing sites that can compromise your personal information. By using Postini Email Security (aka Postini Inbound Filtering), you will block these unsafe emails. Messages received by your employees will not put your privacy in jeopardy, and your overall security will be increased.
