We have migrated the Clientacces last week.

Now SMTP-Clients get a NDR with 554 5.6.1 Body type not supported by Remote Host. It seems that happens only when they write 8bit Messages in Plainformat to some external Maildomains.

The Mailflow is Client -> Exchange 2010 HUB -> Exchange 2003 Frontend -> RemoteMTA

Is there a possible Problem beetwen Exchange 2010 Hub and Ex2003 Frontend and Mailrouting/Convertation? The Message must be converted to 7bit when a REmoteMTA dont support 8BITMIME?

Hi,

Is the remote MTA supported the 8bitmime?

If not, we need to disable the 8bitmime on the Exchange 2010.

Thanks

Allen

Hello Allen,

the RemtoeMTA don&acute;t support 8bitmime.

Can you explain why we must disable this on exchange 2010? On Exchange 2003 we havent disabled this in the past and it works. Should we reenable it on Exchange 2010 when whe completly migrated to exchange 2010 and no Exchange 2003 server is involved in Messagflow anymore?

I try to understand where the Problem is between exchange2010 and Exchange 2003 and why to disable it on Exchange 2010

Thank you
