Spam makes between 90% to 95% of all email on the Internet. This huge number means that most Internet users have to deal with spam on a regular basis. Many email providers use spam filters to sort out most of the spam before it reaches the user's inbox. It is however often the case that spam emails reach the inbox so that the user has to deal with the spam personally.
Desktop email clients and security software often comes with an anti spam component as well to tackle spam on the desktop. That's of no use for users who manage their email accounts on a website but those that prefer desktop software have additional anti spam software at their disposal to block spam from reaching the inbox.
The anti spam software Comodo AntiSpam is such a software program. It is compatible with many popular email clients such as Outlook, Windows Mail or Mozilla Thunderbird.
The anti spam software uses Passcode authentication to protect the email accounts from spam. This anti spam protection basically uses a whitelist of senders that are allowed to send email to the user. Every other email sender that is not in that list needs to reply to an email that are automatically generated before the original email will be accepted. It is like captcha for email.
The program walks the user through a five step setup process that consist of the following configurations:
Comodo AntiSpam runs in the background from that moment on. It will automatically send out the passcode email verifications to senders who are not on the authenticated sender list.
New email accounts can be added to the program at any time. It is furthermore possible to add email senders and domains to a blacklist so that their emails are blocked automatically from that time on.
How effective is Comodo AntiSpam? That depends on a number of factors. Spam is usually send out automated and a great deal of spam messages can be blocked with the passcode authentication. Spam senders who take the time to reply manually to the passcode authentication could however bypass the system. It is also likely that many phishing emails would go through as they fake the sender's email address.
The verification raises concerns when it comes to first time contacts with legit companies as it is not clear how they will react if they receive a passcode reply email.
Comodo Antispam is nevertheless an interesting anti spam software that works best in addition to other anti spam techniques. The anti-spam software is available for free at the Comodo website.Advertisement
