NmSTMP的属性和办法不多，关键的属性是Host（STMP办事器名称）和PostMessage（包含邮件信息），精确设置了Host属性和PostMessage属性后，就可以用Connect办法（连接办事器）和SendMail办法发送E－mail了。STMP办事器名称应是不消认证的办事器，如smtp.21cn.com Sendmail; procedure TForm1.Button1Click(Sender: TObject); begin with Nmsmtp1 do begin Host:=办事器名称; PostMessage.ToAddress.Add(收件人地址); PostMessage.FromAddress:=发件人地址; PostMessage.FromName:=发件人名称; PostMessage.Subject:=邮件主题; PostMessage.Attachments.Add(附件文件名); DisConnect; Connect; end; end;别忘了给分！！我快没分了
