Unable to send or receive emails after installing ESET Smart Security

If you are experiencing difficulties sending or receiving email after installing ESET Smart Security, first disable the firewall to see if it is affecting email communication. See the steps below for details:




1. Open ESET Smart Security by clicking the icon in your Windows system tray or by clicking Start → All Programs → Eset → ESET Smart Security



2. Switch to Advanced Mode by clicking Toggle Advanced mode in the lower left corner of the main window, or by pressing CTRL + M on your keyboard.



3. In the left column, click Setup → Personal Firewall → Disable filtering: allow all traffic.

The Firewall is now disabled. Check to see if email can be successfully sent and received.

If the issue is not resolved, the firewall is not the problem. Please verify that:

*
You have an active Internet connection
*
You can send/receive e-mails when accessing your account directly through the website. (ex: http://www.hotmail.com/)
*
Microsoft Outlook has been configured correctly to retrieve your e-mail
*
No other firewall is currently installed



Modifying Personal Firewall Settings

If disabling the firewall resolves the issue, adjustments need to be made to the firewall rules or the rules need to be returned to default. Follow the steps below to adjust the firewall settings.


1. Open ESET Smart Security.


2. While in Advanced mode, click Setup → Personal firewall and then click Advanced Personal firewall setup... at the bottom of the main page (See Fig. 1-2 below).
