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: firstname.lastname@example.org
Mailing failed. Details:

I am using Blog-Power software to connect to my Weblog Typepad.com( http://dentalcarehygiene.typepad.com
through my Outlook Express E-mail.
Your advice will be appreciated.
