Can't send Emails from Eudora 6 to ISP external mail server

[mattiske]

I am trialing WinGate 6 on our new ADSL connection. We have been using WinGate 3 for the last N years in a dailup connection.
WWW proxy works ok. I can receive emails ok. I cannt send emails.
We use Eudora 6 client (paid mode) with external mail server hosted by ISP.

These message appear in SMTP Server.log
