Anti-Spam
Spam Problems?
According to this Wikipedia aritcle, spam accounts for over 80% of all emails sent in the world. It's also a well known fact that the older your company domain name is, the more spam it will receive. Spam costs time and money because:
- When there is an influx of spam, mail servers are distracted from their normal duties and have to account for extra processing time. This slows the system down.
- Employees have to spend time sifting through spam and deleting it.
Most companies therefore require a cost-effective anti-spam solution.
Defence 1
If you are using POP3 protocal, RatwareUK can implement Spam Assassin, a superb weapon against spam. Read more about Spam Assassin here.
Defence 2
If you're collecting mail at your own SMTP server, RatwareUK can analyse your mail server and implement procedures such as intelligent message filtering and reverse DNS. This should prevent spam reaching the user, however, filtering from the server still uses your company's processing time.
Defence 3
RatwareUK's Mail Relay Server allows you to run your own mail server while RatwareUK filters spam through heuristics and DNS-based blacklists and discards viruses. This is highly efficient for the company. RatwareUK hold and store your mail if your primary mail server goes down, and we can also deliver your mail to an alternate port.
