Send SMTP Mail Message: No such host is known

[slimshadysingaporean]

Hi everyone, for this send SMTP message activity where we used Gmail, it did not manage to work on my friend’s computer. We had tried using port 25,587,465, had already turned on IMAP in our Gmail account and turned off less secure app access. With the use of the smtp.gmail.com server, it still did not work Did anyone find a way to solve this issue? Thank you!

Hi… @bbd2dd21ca331143ce77 Issue has been solved, have you enabled less secure apps in your gmail account ?. Kindly enable less secure apps then you will able to send the mails. use below link to enable. https://myaccount.google.com/lesssecureapps?pli=1 [Mail]

May be try testing the SMTP via powershell to confirm it is working there? this seems to be an incorrect server parameter issue

Just asking: Can you ping the host? Can you telnet the host on that port?
