Hi - The system log is showing errors for email sending with the following text:
"Unable to email via SMTP: Failed to add recipient: "
I thought the issue might be not using authentication in the SMTP settings for the email address, but when I try to set Authentication Required to 'Yes' and save, I get the error "Unable to log in. Check SMTP settings." - The thing is, the SMTP settings I'm using are the same as those I use in Thunderbird, which has no problem sending.
Any help would be appreciated
