Owl550

Owl550, developed by Helianthis Arkechene, is a Security program specializing in Privacy. Available in its latest version 3.1, it operates on Windows Vista, and 7 and offers a robust protection system against spam emails. This Shareware software provides users with unmatched control over their email management.

Designed to act as an anti-spam tool, Owl550 allows users to create and choose a return formula for unwanted emails. This can mimic the well-known "Undelivered Message" response used by email servers to indicate that an address is non-existent. Additionally, users have the flexibility to modify the time interval between two server reads, which can optimize the program’s efficiency based on personal preferences.

One of the standout features is the ability to see email content before download, giving users the power to vet and manage their emails more effectively. The application also offers preset and save options for friends and undesirables, sorted either by address or by server. This level of customization is vital for maintaining a personalized email management system. Moreover, Owl550 includes configurable sound alerts for different email types such as friends, undesirables, unknown senders, and connections.

Further enhancing its functionality, Owl550 allows users to delete and return emails automatically and seamlessly import existing accounts from Thunderbird, ensuring a smooth transition for new users.

It’s worth noting that while Owl550 is primarily classified as version 3.1, it operates exclusively as Shareware, which provides some features for free download with the option to unlock the full suite of functionalities upon purchasing a license.
