Bigmail allows you to easily and securely send and receive oversized attachments even when your corporate email or the recipients' email servers don't allow for large emails. Bigmail can be used as an Outlook add-in, or independently of Outlook. Bigmail is freeware but does require user registration. Freeware users are allocated 20 megabytes on the Bigmail server to store attachments which will each have a two day expiry. Version 1.5 may include unspecified updates, enhancements, or bug fixes.
