- Spam Arrest cans just about all spam using challenge/response filtering of unapproved senders
- A flexible and comfortable web-based interface makes Spam Arrest universally and easily accessible
- Spam Arrest offers 1 GB of online storage
- Spam Arrest does not use a spam filter to challenge only senders of mail that is not certainly spam
- Spam Arrest suffers from the problems common to challenge/response filters
- Spammers can use commonly approved addresses to make it past Spam Arrest
- Spam Arrest checks and cleans up to three POP, IMAP, AOL and Hotmail accounts periodically.
- Works as a POP proxy service between your email client and your POP email account.
- In addition, Spam Arrest provides 1 GB of online storage, webmail, and a fresh email address.
- Spam Arrest puts all mail from unapproved senders in quarantine.
- The Spam Arrest quarantine folder can be accessed via the Web, and senders can be approved easily.
- Additionally, Spam Arrest sends challenging messages to new senders, replying authorizes them.
- Spam Arrest supports mailing lists by approving a To: address instead of individual senders.
Fetching new mail from up to three POP, IMAP or Hotmail accounts every two minutes, Spam Arrest automatically removes mail from blocked senders. Unknown senders get a challenging message which they can use to authorize. Alternatively, you can authorize senders manually. In addition to protecting existing accounts, Spam Arrest also gives you a brand new email address plus 1 GB of online storage and a usable if a bit slow web-based email service to use it.
Unfortunately, Spam Arrest suffers from the problems of challenge/response architectures. The challenging messages can be annoying or puzzling to individual senders and a real challenge to legitimate bulk mailers, and if spammers use a sender you have approved they'll get through without problems.
