Hi - Every 2-3 days I start to receive an error message from Norton when I send emails from my Windows Live Mail account saying:
451 qq temporary problem (#4.3.0)
This appears as soon as I click send and the message falls into my sent box but doesn't actually get sent. I've contacted my outgoing email server provider (3 mobile) who tell me it's a problem with Norton. After about 24 hours the problem seems to resolve itself but sure enough will reappear after a couple of days. This problem only arises when I use my mifi whereby I use 3 mobile's outgoing servers to send my emails. If I use another WiFi, the problem doesn't arise. I don't change any settings, the outgoing mail port is 25.

Welcome. Can you please turn off the outgoing email scan option in the Norton and then try to send the emails. Settings --> Network --> Message Protection --> Email Antivirus Scan Configure --> Remove the check mark next to Scan Outgoing Emails
--> Now send a test mail and check.
An user in here had solved a similar Problem by contacting his ISP.
