we use C600 Machines , and every time a msg size is exceeded
the customer becomes a Notification that your msg size is exceeded.
BUT i cant see any entry in Ironport Log files
ONLY this:

Mon Mar 3 22:40:19 2008 Info: ICID 246653156 Receiving Failed: Message size exceeds limit

What version of AsynOS are you running? That was taken from a box running 5.1.x.

I believe both of these happen on the IronPorts, it depends more on the sending MTA than the recieving IronPort.

It all depends on if the sending MTA honors the EHLO SIZE limit feature and does not attempt a message larger than the advertize max. In this case you have a simple ICID xxx close, because the sending MTA did not hit the size limit it simply closes the connection and generated a NDR to the sender saying the message size was beyond what the recieving MTA would accept before it even attempted to send the message.

Second case is when the sending MTA does not use the EHLO SIZE limit feature and sends the message forcing the IronPort to hard reject the message once it hit the max size limit, hence the ICID xxx Receiving Failed: Message size exceeds limit. Same NDR gets generated, but after the wasted bandwidth. :(

BIG thanx to both of you for the replay

But the problem i have is in the MAIL-OUT Flow Policy.

In this case when a customer try to Relay a MSG bigger than the size allowed
in his Policy he becomes a NDR Message(Message size exceeds limit) and the connection glosed.
I see nothing than a simple ICID xxx close.


For INBOUND Messages with a BIG size i see this in Logfile:
Mon Mar 3 13:56:10 2008 Info: Bounced: DCID 108290091 MID 76963682 to RID 0 - 5.1.0 - Unknown address error ('552', ['5.3.4 Message size exceeds fixed limit'])



BUT what shall i do to see a MSG in logfile for OUTBOUND ?
