For some reason I am getting this message bounced back when a a large message is sent to a customers SBS 2008 server

Have double checked the receive connector settings and thats set for 30MB on each on the connectors and the maximum per mailbox is set to unlimited.

Have checked against this article


Was working til recently (not sure when it stopped working)

Anyone got any ideas?

The receive connector is only one spot there are several spots you need to change.

This will give you some ideas.

This article is more GUI thus easier for me at least to follow.

You do not ahve a 2003 Exchange in your orginization do you?

Organization Configuration | Hub Transport | Global Settings tab | Transport Settings | properties | General tab

Server Configuration | Hub Transport | select a Hub Transport server | Receive Connectors -> select a connector | Properties | General tab

Organization Configuration | Hub Transport | Send Connectors -> select connector | Properties | General tab.

Recipients | Mailbox -> select mailbox (or select another recipient type such as a contact or mail user from the corresponding node) | properties | Mail Flow Settings tab | Message Size Restrictions.

You are checking on the Receivers server and not yours yes? And of course the message IS under 30MB yes?

Message is coming from customers server

Test message Im sending is about 25MB

Just done a reboot of server instead of restarting transport service. Dont think it will make any difference but at least shows the customer I am doing something
