v1.1 of plugin: " 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... "
This plugin contains the "freeware" version of JBMail - the difference between this version and the shareware version of JBMail is the ability to use and save more than one mail profile. Otherwise, the "lite" version has no other limitations. If you have the full version, just copying that into the files\ should work fine. The help page was converted to plaintext on the menu.
