SendMail didnt send an email
I ran a runtime program that I made on a different computer to my regular one.
It was to send emails to a list of people (the progam script uses the sendmail command).
They all sent successfuly except one. It failed on a repeat try.
I investigated and found that the email address was fine.
I checked further and found that the email client was Windows Mail.
Windows Mail didnt have this particular person as a contact, so I added the person as a contact and retried the runtime program.
This time it worked fine.
This is bad news and can't be normal. Can anyone help me out?
