Hello,
I'm trying to send email using synapse.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TEmailForm.Button1Click(Sender: TObject);begin     if
SendTo('info@brio.co.kr', leTo.Text,                leSubject.Text,  
            'webmail.brio.co.kr',                Memo1.Lines)     then
ShowMessage('Mail Sent')     else ShowMessage('Failed');end; 
leTo.Text is the recipients' addresses. The mail is sent only when the
domain of recipients are the same as that of sender. so I can send
email to abc@brio.co.kr, but not to  any other address like
def@gmail.com.

Any possible reason? It may be not the problem of Lazarus or Synapse.
Instead it may come from mail server (in this case
webmail.brio.co.kr). 

Interesting thing is that I could send email to other addresses in the
morning.

I think I found the reason --- some mail servers require SMTP
authentification. So I have to use SendToEx instead of SendTo.
