I recently upgraded the Domino servers from 5.0.12 to 6.5. We are using SMTP mail routing through an Exchange server which is failing in some cases after the upgrade. If I send an email with a few sentences, it goes through with no issues. If I send a longer email containing URL’s, etc (No graphics), I receive the following error in my Outlook email:
The Microsoft Exchange Server received an Internet message that could not be processed. To view the original message content, open the attached message.
Once I open the attachment, the conversion for this email is set to:
Content-Type: text/plain;
charset=utf-8
Content-Transfer-Encoding: base64
On an email that is processed correctly, the header displays the following:
Content-Type: text/plain;
charset=us-ascii
Content-Transfer-Encoding: 7bit
Any ideas as to why it’s failing?
Thank you.

If you take the Exchange error at face value and assume Domino didn’t actually send a corrupted message, it looks to me like Exchange is having a problem translating one of the stadard encoding formats used for SMTP mail.
I don’t know much about Exchange, but could it be that it simply doesn’t have the UTF-8 stuff installed or configured? I’d be surprised if that’s true, since base64 is pretty standard, but wouldn’t hurt to ask Microsoft or an Exchange admin who knows their SMTP standards.

Thank you for your reply. I saved the SMTP outbound message that Lotus generated to a file and then used telnet to send this directly to our Exchange server - It worked. When I used the server utilizing ‘Tumbleweed’, it was failing. I’m still trying to see if our Exchange folks made any changes to Tumbleweed configurations. To me, this seems like there is no relation to our Lotus upgrade.
