GREmail is a professional email preview client utility with SSL/TLS support designed to quickly and easily maintain many POP3 accounts from a single Windows application. Includes a rule manager that among other functions allows the user to classify messages to focus on important messages or to quickly identify and delete SPAM. Every account is automatically scanned after a specified period of time or the user can press the Check for Email button (F5 key) and the number of messages with their account names will be shown in a task bar window. The program is organized with tabbed dialogs so that the user can quickly jump to email messages, rules, account or the program options with one click. Once email accounts have been scanned, the user can see the messages in the Email tab. The bodies of the messages can be partially or totally retrieved. Only the headers are downloaded just to display the message summary: message number, size, subject, from, to, cc, reply to, date and the rule that has matched if any. Checked messages are ready for being deleted with a single click. If a message is deleted in error, there is a 30 second delay to undo deletions account by account. GREmail is a real time saver to kill the daily SPAM. If a message seems doubtful it can be safely Previewed using an integrated email viewer that will not automatically open attached files or download web contents that can be unsafe. The viewer supports Text and HTML view modes. Attached files can be saved on the local disk. A message can also be forwarded to any user supplied email address and this inbox will receive the message as if it was originally sent to it. Naturally the user can Reply to (or Reply to All) a message if the user wants to quickly send a note. A customizable button allows for easy integration of GREmail with the user's default mailer so that when the Email Preview is completed the default mailer will receive and store the good messages. This is must-own software for anyone.
