email size restriction problem for exchange
Posted on 2011-09-09
We have a single sbs2008 wich is running exchange. We have a user that needs to receive relatively large drawing attachments. We find that anything over 7Mb is bounced back as being over the allowed size limit.
I have checked in several places for this but cannot find out where the restriction is implimented, as they are all currently not set.
Can anyone help track down where this is controlled?
The NDR was as follows :-
Reporting-MTA: dns; relay.pcl-ipout01.plus.net
Status: 5.0.0 (permanent failure)
Remote-MTA: dns; [18.104.22.168]
Diagnostic-Code: smtp; 5.1.0 - Unknown address error 552-'5.3.4 Message size exceeds fixed maximum message size' (delivery attempts: 0)
