Exchange 2010 Rejected emails

Question

All,
I am trying to find a way to get more detail when an email is rejected by SCL.  We have a client that out of 100 emails 2 got rejected and I am looking to find out why.   I can submit the error, but it just says that SCL got tripped and Exchange
dropped the email.
I have read another post that the SMTP receive log files on the transport connector would provide more detail, but if I turn this one is there any negative side affects other then a log file?
If anyone has an idea much thanks.

Hi Mays
First you can check by analyzing thorough message headers and see the reason why the emails are rejected
You can enable pipeline tracing for the emails which are getting rejected  and check if the emails are getting stripped
Get-TransportServer | Set-TransportServer -PipelineTracingEnabled $True -PipelineTracingPath "C:\Pipeline Tracing Logs" -PipelineTracingSenderAddress
[email protected] -ContentConversionTracingEnabled $True
There is no harm in enabling the verbose logs on the receive & send connector until there are more transactions happening per day and you run out of disk space . Ensure the drive which holds the protocol log path have enough space if your environment
is big and have huge mail transactions happening in a day
