450 5.2.3 Msg Size greater than allowed by Remote Host
Posted on 2012-08-23
SBS2008 + Exchange 2007 For the first time, a customer needs to send us an attachment which is 15Mb. When he reported that his mail was bounced by our server with the above message, I increased the limit to 120mb. I've done it in 2 places. Firsly I done it in:
Organisation Config->Hub Transport->Global Settings->Transport Settings
and i've done it in all the Recieve Connectors in:
Server Configuration->Hub Transport
When it didn't work immediately, I googled the problem and found a page which said that if I change these settings, it can take several for them to take effect. Four hours later our customer still cant send his 15Mb attachment. Did I miss something here?
