Smtp protocol returned a permanent error

I have problem sending internet mail with Notes 6.5.4 and Notes 7.02; the error returned by the ISP server is the following : smtp protocol returned a permanent error.The same operation with the same Account document configuration with Notes 8.01 works fine.

What can I do for my customers that currently use Notes 6 or 7.

The problem is probably due to the CommandAUTH operation that is not accepted by the ISP server and cause a Disconnect operation.

Any suggestions will be appreciated

Add this line to your Domino Server Notes.INI:

SMTPClientDebug=1

Restart the Router and send a couple of messages. You will see that the Notes Log will be giving you much better results concerning SMTP traffic which ought to help with the troubleshooting.

I’am sending Internet mail directly from Notes Client without a Domino server.

Use SMTPClientDebug=1 in your Notes.INI. This TechNote explains how to set it up and use it:
