I assume you can't send email from TDS-3. If you can send email with your regular emailclient, and you are using the same smtp server then it should work. The only reason that it wouldn't work is, is that your firewall is blocking the smtp of TDS-3. that is: tds3smtp.exe So: TDS-3, Configuration, servers, fill in the smtp-server you are using in your mailclient and your emailaddress and cklick on 'test email' button. If that doesn't work, look in your firewall logfiles, (perhaps) it will show you that it has blocked tds3smtp.exe. Or ... you are using PG and you've blocked it there, check the alerts to be sure. If so, give it access. Good luck..
Submitting malware to TDS; (intrusion)alerts sending to admin on a remote location or to your email; other forwardings, using the smtp plug-in for (anonymous) email, etc.
