Need fix on OBIEE side for below error..
OBIEE 11g: Agents (iBots) With Large Attachments Fail With Error '[nQSError: 75009] Failed to send message. 5.2.3 Message exceeds maximum fixed size' (Doc ID 2024135.1)
You reference a MOS Doc which clearly states that this has nothing to do with OBI and all to do with your mail server.
Not sure what kind of answer you are expecting. We can't change the setup of your mail server - especially since you don't specify what your mail server is.
Talk to your mail server administrators!
Fix: Don't try to mail large datadumps from OBIEE, it's an analysis tool not a datadump utility
Or rather: Don't try to mail big datadumps at all
