If you're running your own mail server, go check the logs, as there is 
probably a message in it about this.  If you're not running your own 
server, I would imagine there is a conversation going on something like 
this, where CLIENT is your MUA (e.g. Mail, Eudora, Entourage) and 
SERVER is the mail server that your mail goes through:

CLIENT:   EHLO <hostname>
SERVER:   200 Hello, <hostname>
CLIENT:   MAIL FROM:<someone> SIZE=999999999
SERVER:   552 That's too big.  Go away.
CLIENT:   QUIT

Depending on the client and that you use and the MTA you are talking 
to, you may or may not get some feedback about this failing.  If you 
are using Mail, which version are you using?  When I try sending a 10MB 
file, I get a nice bounce notice from my mail server saying that the 
message size exceeds the allowed limit for the server I'm trying to 
use.

I don't think you're going to find many (if any) MTAs that will pass 
e-mail as large as you want to send; some MUAs won't handle it either.  
E-mail is really for sending small amounts of data, not vast quantities 
like 300MB.  Snail mail a CD of this data, if you have no way to share 
via FTP, HTTP or rsyncX.

Hope this helps,
