http://www.avast.com/support-contactsWill you please allow me to double check the redirect settings?
First, I need the following questions answered.
1. What port is used by your email provider?
2. What encryption is used (ssl or tls)?
Please post a screen print of the areas that I have attached.
The first is of the SSL mail accounts located in the mail shield expert settings.
The second is your email client properties advance tab.
The third is located under Avast settings/troubleshooting/redirect settings.
