The error "Unrecognized Server Response" is returned to the Order Manager from a third party ActiveX control that our system uses to send email. Typically the error is due to a malformed email address or a domain in the email address that cannot be resolved by the SMTP server. If the Order Manager receives this error, it will not send email for that order.
If the program is sending a batch of emails, such as when it processes tracking numbers, it should continue with the process. Other types of errors may cause the processing to stop completely (or allow the user to tell the system to continue). If that happens, you should be able to re-start the process. For example, to re-start processing of tracking numbers, return to the Main Menu, then go back to the Maintenance Menu and click Process Tracking Numbers to continue where the system left off. Note that you may also receive the error again if dealing with a bad email address.
Beginning with version 4.004 has code added to attempt to send up to 10 times whenever these errors are encountered and if the email does not go through, the user gets a dialog box displaying the potentially bad email address so they can try sending the message using their standard email client or if the SMTP server closes the connection due to too many emails sent in a single session (very common now due to anti-virus and spam concerns by the SMTP hosting company), the system will establish a new connection and continue to send. Should an error occur that cannot be resolved, the error message displayed will have additional information to aid the user. Unfortunately we cannot avoid these types of errors in the system because the errors are not within the Order Manager but generated by the SMTP server. We can only attempt to handle those we can and inform the user when an error occurs that cannot be handled.
If one of these errors occurs:
New email method error: Unexpected server response
New email method error: Server closed connection
New email method error: Socket error
Here are some things you can check:
Check for bad email addresses
Check the outgoing SMTP port. You may be able to use a port other than the default, which is port 25. Set this in the system parameters SMTPServerPort and SMTPServerPort2
Check your SMTP authentication settings in the parameters SMTPUserName1 and 2 and SMTPPassword1 and 2. If your SMTP host does not require them, make sure those parameters are empty. If your host does require them, make sure they are correct.
Check with your ISP to see if they block outbound SMTP other than their own.
