How exactly does Flexfilter work?
All incoming e-mails are scanned by various specially configured anti-spam tools.
A number of steps from the process follow below:
Checking whether websites or domains have been blacklisted:
Our servers maintain an up-to-date list of known, aggressive spammers. We combine this list with the lists provided by various anti-spam organizations.
Scoring system:
Our scanning technology uses a scoring system that gives e-mails points based on a number of criteria. If an e-mail is given too many of these spam points, we mark it as spam.
Checksum technology:
Central e-mail servers monitor e-mail traffic through the Internet. The servers use checksum technology to track and monitor e-mail messages. If a large number of e-mails with the same checksum are detected, these will be analyzed and marked as spam.
Sender check:
Special algorithms are used to verify the sender of an e-mail message. A number of aspects are checked, including the validity of the e-mail address used by the sender. Other checks are more complex and relate more to the SMTP protocol.
Spam run restriction:
This is used to stop DoS attacks and dictionary attacks on domains.
Files:
A number of file types will always be blocked. For example:. VBL files.
Anti-virus:
All incoming e-mails will pass through various virus scanners. By constantly updating our scanners, we always have the most recent virus definitions.
Phishing and fraud:
By carrying out special checks, we can stop e-mail messages from con men getting through. These individuals use e-mail to try to obtain confidential information (credit card details, bank details and personal details).
A top-quality anti-spam filter!
Flexfilter is an external anti-spam/anti-virus gateway that checks all incoming e-mails before they arrive in your e-mail inbox.As a result, server and computer protection improve dramatically, as spam and viruses stopped by the Flexfilter will not reach you.

Flexfilter is also a backup e-mail server (batch SMTP)
If you are looking for a batch SMTP solution, Flexfilter is the best choice for you. Flexfilter is also a batch SMTP server.Batch SMTP is an e-mail backup solution. If your e-mail address or server is down, e-mails will remain in Flexfilter until your e-mail address or server is up and running again. At this time, all of your e-mails will be delivered to your e-mail address. So, even if your e-mail server is down, you will never lose any of your e-mails! Flexfilter can be used solely as a batch SMTP server, but can also be used as an all-in-one batch SMTP and anti-spam solution.
