ian@kirbyfooty.com was the right email address.
Anyways, I retested getting Kirby Alarm to send the email, but with the same content as you.
It worked ok at my end when using Thunderbird.
I then tested it again, but this time used Outlook to read the email.
It did not work in Outlook.
Attached are screen dumps of the alarm setting, and the resulting email.
To be honest at this stage I do not know what to do.
I don't know if it is a problem with Kirby Alarm, or a problem with Outlook.
