I did changed from Logon- Use Same Setting as my incoming mail server, to Logon Using Account name and Password,
Using Secure Password Authentication.
I still receive "504 mechanism not supported".

The following is the copy of error sign:
Building email with subject: Test subject line [Receiver Email:]
Sending email...
Mailing failed.  Details:
504 Mechanism not supported

I am using Blog-Power software to connect to my Weblog
  through my Outlook Express E-mail.
Your advice will be appreciated.

    "Secure Password Authentication" is not what you think it is. It is a special type of function supported on Windows NT mail systems, and *specifically* has to be enabled on that system (i.e., a type of challenge/response mechanism).

    It is *NOT* the same thing as say. the difference between http:// and https:// when browsing a webpage.

    To get it to work, you'll need to disable that.
