Conflict with wp_mail function when both Access and WP-SES plugins are used

Symptoms

When both plugins are active we receive the message: “Another plugin did override wp-mail function. Please de-activate the other plugin if you want WP SES to work properly.”

This happens because the file wp-includes/pluggable.php is needed by Access and it declares the wp_mail function. This function is also commonly declared by other email-related plugins like WP-SES. This situation is almost impossible to be avoided as it’s defined in a WordPress core file.

Workaround

There is currently no solution or workaround for this problem.
