I am using the adobe developers toolbox and I am sending an email from a form that inserts the data into the database. The problem I am having is when the transaction executes it fails because the email is being stopped by the server from sending the email. I would like to know if anyone has come across the following error
Error sending e-mail.
E-mail couldn't be sent. Error returned: Failed to send data [SMTP: Invalid response code received from server (code: 503, response: valid RCPT command must precede DATA)]. (EMAIL_FAILED)
tNG Execution Trace - VIEW
+ tNG_insert.executeTransaction - execute sql
I have sent this to my service provider and they insist it is the source code. If you use a simple mailer for php it sends the email.
I am sure it is probably a setting but am not sure. If anyone has come across this error and knows how to tweak the code of change the settings please let me know.
Ideally I would like to use the toolbox as the mailer should work as it is a standard VPS Linux server with PHP that I am using
