Spamjadoo applies almost a dozen levels of checks and validations to
every mail before letting it through to your Inbox. The powerful ESP
engine incorporates over 100 rules at the server, domain and
user levels. A highly optimized architecture ensures virtually no
delay in mail delivery. No other product is as thorough or as fast. ESP
combines a number of innovative techniques to avoid the problems that
plague other products based on content-filtering,
challenge/response, disposable mailboxes, or any other technique.
State of
the art techniques (including SPF, DNSBL, DHA protection, SMTP Auth
– over 100 rules across a dozen levels) are applied first.
Then, a validation is run against your list of trusted senders. Spam
always fails these checks, hence it is blocked – at the SMTP protocol
level, without ever needing to inspect (or even receive) the content.
This is the magic of ESP – spam is blocked before it can be sent !
