Just upgraded to Exchange 2010 from 2003. We are a forensic CPA firm and send/recieve lots of big attachments. Having issues with email being bounced back. Here is a sample code: #< (#5.2.3 smtp;550 5.2.3 RESOLVER.RST.RecipSizeLimit; message too large for this recipient> #SMTP#).
So after some investigation I did these two commands via the Exchange Managment Shell...FYI--LCMAIL is the name of our Exchange server
Set-ReceiveConnector -identity "LCMAIL" -maxmessagesize 40MB
Set-SendConnector -identity "LCMAIL" -maxmessagesize 40MB
Additionally, I contacted our ISP which is a cable company and the said the max attachment size is 20mb...so I figured that I would double it as shown above.
Then I did this command:
get-receiveconnector | select identity,maxmessagesize
Here's what was returned on screen
LCMAIL\Default LCMAIL 40mb
LCMAIL\Client LCMAIL 10mb
SO...HERE's my question: what is "Client LCMAIL" and how can I change it from 10mb to 40mb...as I assume this is the culprit and reason why some of our clients are getting bounce-backs when sending large attachment(s) with email.
Your insite and help would be most helpful...many thanks in advance.
