BufferZone vs Mailrelay

BufferZone

Security & Privacy

BufferZone is a free firewall program that protects your computer from malware, hackers, and internet threats. It works by isolating your web browser and email client into a virtual container, preventing threats from accessing the rest of your computer if you happen to visit an infected website or open a malicious email attachment.

Mailrelay

Business & Commerce

Mailrelay is an email delivery service designed to improve email deliverability. It helps avoid spam filters and blacklists by sending email through its own IP addresses with good reputations.
