Mailonator is a system that guarantees the delivery of email attachments quickly and securely and avoiding any restrictions that might be in effect for the email recipient. Mailonator software installs on a server, so the email service and client tools never need to change. It works by intercepting email messages, stripping the attachments, and storing them on a server. In addition, Mailonator sends you an email notification when recipients download your attachment, and provides system administrators with usage statistics.
Bitvector is a C library that allows you to use strings rather than ints for internal flags. On many platforms, ints are limited to 32 bits and are thus limited to 32 flags available for a given flag variable. Bitvector uses a resizing char array for flags, allowing much greater flexibility for flag management.
