Most corporate networks have a larger IT budget and can afford expensive anti-SPAM devices. Over the past five years, some of these features are placed into less costly devices, yet they are not easy to install and may not help the TYPE of SPAM your company receives.
A new SPAM tactic exists wherein emails are delivered from the same user or from someone within a company, with fake forwards and responses.
This has grown into a problem because most technologies to prevent SPAM are designed for filtering OTHER ‘senders’ and not the owner of the email account. The technology assumes all email is real and good from the owner. This has been taken advantage of through SPAM technology.
A new initiative has been put together to fix this problem. It is called OpenSPF, Recently, some ISP ‘s hosting your domain actually adopted this to improve the quality of their email delivery – to reduce SPAM significantly. Additionally, your ISP can allow you to put your custom SPF entry into your MX record.
