Resolving the issue: 5.3.4 Message size exceeds fixed maximum message size
Submitted by jasonslater on April 9, 2008 – 2 Comments
We recently discovered that several emails, we were expecting, were being rejected by our Exchange Server 2007 and giving the following response:
SMTP command failed when talking to server.domain.com: <<< MAIL FROM:host@remotedomain.com SIZE=16164910
>>> 552 5.3.4 Message size exceeds fixed maximum message size
The resolution was to go into:
- Exchange Server Management Console
- Organization Configuration
- Hub Transport
- Locate the appropriate Receive Connector
- Adjust the value of the Maximum Message Size (KB)
Loading ...
after trying your solutions I found a better workaround.
if you open exchange management shell
do the following:
get-receiveconnector
select the receive connector identity for which you are changing this setting. in servername\identity format
then do the following
set-receiveconnector -identity servername\identity -MaxHeaderSize
128kb (or a higher value)
experiment with this until you do no longer get the error.
to view the current maxheader size:
get-receiveconnector -identity servername\identity |list
cheers,

Thanks for the pointer Marco.
