Question : Unable to send and receive 20MB in Exchange 2003

Hello

I have set send & receive size in Global Settings from default 10MB to 20MB.

I try to send email with attachment file 12MB using gmail to two accounts: my account and administrator account. I received NDR report.

Was I miss out anything?
