Semd mail using gmail SMTP server (wodSmtp)

Hi,

I am currently evaluating the wodSMTP Active X control.
I tried the example in Delphi exactly as it came and it worked for me.
I then ported it into my own program, and again it worked.

Line of code:

wodSMTP1.SendSimpleAttachment('xxxxx@gmail.com','yyyyy@asl-solutions.co.uk','Test message','This is just a test message','C:MCCDATA' + sRTFFileName);

But when I put in the various properties as specified in previous questions and answers, it failed. This is what came up in the Memo box:

Starting to send
Connecting to the server.
Connecting to: smtp.gmail.com

Negotiating SSL encryption.
Established SSL encryption.
Sending greeting to the server.
Connected to the server.

Sending MAIL FROM command.
Connected to the server.
Not connected.
DISCONNECTED

Disconnected, will retry.

After that I copied the contents f the box and reset the prog.

Question is How can it work with minimal info but fail when correct info put in?

I use Outlook normally and have Gmail as my default. But the end-user does not use Outlook - only Gmail from within IE
