Email Error 5.3.4

I am confused about something and was hoping you could clear it up for me. I am getting the following undeliverable message when I try to send a message with a very large (30MB+) attachment:
Your message did not reach some or all of the intended recipients.
The following recipient(s) cannot be reached: on 11/13/2008 1:39 PM
This message is larger than the current system limit or the recipient's mailbox is full.  Create a shorter message body or remove attachments and try sending it again.
<mail.MYCOMPANY.COM #5.3.4 smtp;552 5.3.4 Message size exceeds fixed maximum message size>
The question I have is regarding the "current system" part. Obviously, the "recipients mailbox" is remote, but is the "current system" remote or is it referring to my system?

The message is a generic one and as such is covering all the bases.
"Current system limit" refers to your mail server.
This doesn't indicate that this actually was the problem, it's just posing one of the two most likely scenarios.

That error should be coming from the system named mail.MYCOMPANY.COM in your example. If mail.MYCOMPANY.COM is the name of your mail server, then that is where the max message size limit is being reached. If that's not yours, then most likely it is the recipient's mail server. 30MB is VERY large for an email. Many systems default to a max of 10MB or so.
