How to Find an Outgoing Mail Server in a Computer
When you set up a new email address through your Internet service provider or a third-party email provider, you will need to know the incoming and outgoing mail server. Any time you send a message from your email client, such as Microsoft Outlook or Mozilla Thunderbird, your computer accesses the outgoing mail server to forward the message to its recipient. You can locate the outgoing mail server by accessing the proper menu in your email client.
Click "Tools" and then select "Email Accounts." Click "View or change existing email accounts."
Click "Next." Click the name of the mail account you need to find the outgoing mail server for. Select "Change."
Locate the "Outgoing Mail Server" text box at the right side of the window. Note down the outgoing mail server.
Click "Tools" and then select "Account Settings." Click the "Outgoing Mail Server" link at the left side of the window.
Scroll through the list of email accounts and highlight the specific account you are looking for. Click the name of the account and choose "Edit."
Find the "Server Name" text field at the top of the window. Note down the outgoing server listed in the text field.
