Session size exceeds 10240 Kb error message - Exchange 2003
Posted on 2006-06-07
We are having problems sending messages to a remote organisation. The error message is as below -
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<mailserv.mydomain.co.uk #5.5.0 smtp;552 188.8.131.52: your total session size exceeds maximum inbound size of 10240 kilobytes>
Sometimes, there is an attachment, other times not...but, in each case, any attachment was not larger than 3 MB's.
I cannot seem to find anything on the web for this and certainly haven't seen this before.
Under my SMTP Virtual server on mailserv.mydomain.co.uk properties there is no session limit set.
