After a clean install of Xampp 1.8.2, I found that Mercury Mail no longer works with a previously working email client configuration (Thunderbird).
After starting Mercury Mail in the control panel, sending test messages in Thunderbird gives the error message
An error occurred while sending mail. The mail server responded: Service not available, closing channel. Please verify that your email address is correct in your Mail preferences and try again
Restoring the complete MercuryMail folder from a 1.8.1 Xampp into the 1.8.2 Xampp then works fine.
Changes to the php.ini file to swap from mailtodisk to use Mercury mail obviously still need to be made to use the simple email form in Xampp
I was wondering if the Mercury mail s/w could be updated to the latest version 4.74?
