JBMail

JBMail is a compact and portable secure e-mail client.
The software has been designed for simplicity, security and "on-line mailbox access" meaning that mail is manipulated remotely and NOT stored locally.
JBMail supports POP3, SMTP, SSL/TLS and all essential mail client features - but it is not "just another" mail client.
Here are some key features of "JBMail":
ï¿­ Security and Privacy. JBMail uses smart technology choices to eliminate the security and privacy hazards found in other mail clients, without sacrificing interoperability. For instance, HTML is stripped to plain text and not rendered.
ï¿­ Full SSL/TLS support. Secure Sockets Layer and Transport Layer Security use state-of-the-art encryption to protect POP3 and SMTP communications from eavesdropping and spoofing. Provided by the industry standard OpenSSL.
ï¿­ Virus protection. Multiple levels of defense against viruses, worms and trojans. Safety features include a file block list and executable file SanityCheck.
ï¿­ Junk mail filtering. JBMail includes powerful junk/spam filtering capabilities, including whitelist and blacklist, heuristic custom filters, and even header pattern matching.
ï¿­ Portability. Fits on a floppy disk; no install required. No local mail storage, and no registry keys created. Messages can be viewed and saved/archived in plain text format to guarantee cross-client and cross-platform compatibility.
ï¿­ Efficiency. Header-based POP3 access lets you read and delete mail directly on server without downloading everything. Light-weight software is nimble even on old computers!
ï¿­ Supports POP3 and SMTP; MIME; base64 and UUencoded attachments; ISO-8859-1 (Latin1) Western European characters; and many other standard features.
