Are there any limitations on what I can send and receive through Cmail?
Yes. Per Google restrictions, you cannot send or receive messages that are larger than 25 MB, or messages containing attachments that are executable files (such as files ending in .exe), even if they are sent in a zipped (.zip, .tar, .tgz, .taz, .z, .gz) format. Please note that the process of adding a file to a message increases its size (by adding encoding necessary for transmission), so if your file is almost 25 MB, you may get a “too big” error message. You can use Cornell’s DropBox to securely transfer files that cannot be sent through Gmail. The maximum file size is 1.5 GB.
