do a quick search of these forumsfor the error cause, MaxReceivedMessageSize, i.e. https://community.emc.com/search.jspa?peopleEnabled=true&userID=&containerType=&container=&spotlight=true&q=MaxReceivedMessageSize+

this has been seen before and answers have been given.

the root of your issue will be that you're using BASE64 in the content transfer profile which puts the content inline with the SOAP XML, and it is going over the maximum defined for WCF in the .config file. A better profile type os MTOM as this appends the files to the message and isn't subject to the same issue
