FSU Email allows you to send/receive emails internally with attachments totalling up to 150MB per email. Most external email providers limit it to about 25MB.
Remember: Just because you can send that 150MB file doesn't mean someone's Gmail account can receive it!
FSU Dropbox allows you to send/receive files up to 3GB in size.
