MailSecurity is a program for the inspection of POP3 accounts. It allows you to check your eMails without downloading them to your local PC, so you may delete mails with dangerous attachments or attachments of a too big size directly on the server (without download). MailSecurity provides features to detect such mails on the server and marks them. You may use MailSecurity also for checking mails from a laptop when you are not at home or in the office. You may decide whether you want to download the mails or just have a look at them. Download them later with your own mail program.
