Not sending email for 'admin setting changed' or 'credit card declined' messages

[HeathenMagic]

Hello there,

Been trying to solve this for a while. When changing the settings in admin, you usually get the standard 'admin settings have been changed' email sent to you. But for a few months, it has been only producing the following in error logs:-

ERROR: Failed sending email to: "The Gem Tree" with subject: "ALERT: Your Admin settings have been changed in your online store." (failed validation)

It also does the same with some instance of 'website inquiry' , and all 'credit card decline' with paypal. It is driving me crazy lol. All other emails are sending out fine, no problem, so order confirmations, create account etc are fine. Just changed to SMTPAuth, and emails are working okay. Just these internal emails, they just seem to fail validation, but not sure why.

I found one or two others who had the same issue, but they still have not found a way to cure it. Appreciate any help with this, maybe somebody found out what it was.

The only thing that changed was hosting platform, but they said it is not their issue, it must be something else.
Thanks in advance.
:-)

Maybe it's the email address to which you're trying to send those messages.

Hey DrByte,
Thanks for your response. Feel slightly stupid now, but not sure which one of us changed this setting:-

Email Address (Displayed to Contact you)

I put in a valid email address and it works! Please delete this thread to hide my stupidity for not seeing this myself lol.

Appreciate you suggesting that. Time for a lie down.........
