SecExMail is certified to operate with all SMTP POP3 e-mail clients, including Microsoft Outlook, Netscape Mail, IncrediMail, Pegasus, The BAT, Eudora, and Calypso. SecExMail protects against cryptanalysis at the protocol level: e-mail subject lines are encrypted. All attachments to secure messages are autoencrypted, including their file names and MIME type information. SecExMail is built on the Open SSL secure socket layer library.Now includes automatic key exchange and powerful html filtering to protect from malicious email.
