I have some issue regarding send test email. All email account credentials is valid and i am able using third party email software within the same machine to deliver an email. However, when i tested in smartstore email account settings, i got this error respond failure sending mail. * Unable to connect to the remote server * An attempt was made to access a socket in a way forbidden by its access permissions XXX.1XX.XX.XX:587. I did uncheck the use default credentials option inside the settings. Below is some error snapshot, and please advise how and where is missing some email settings configuration. Thank you.
