How to access Yahoo Mail with SeaMonkey

Updated April 17, 2017

SeaMonkey is an application that functions as an all-in-one Web browser, email client, newsgroup and feed aggregator, IRC chat client and HTML editor. Based on Mozilla source code, it currently supports Windows, Mac OS X and Linux. Users of the premium Yahoo! Mail Plus service can use a Post Office Protocol (POP) to access email in SeaMonkey without using the Yahoo! email interface.

Click "Window" from the SeaMonkey menu, then "Mail & Newsgroups". If you have already set up an email account in SeaMonkey, the "New Account Wizard" dialog will not appear. Click "File", "New", then "Account" to start the wizard.

Select "Email Account" in the Account Wizard dialog, then click "Next".

In the "Your Name" box, type your name as you wish it to appear in emails you send. In "Email Address", type your full Yahoo! Mail email address, then click "Next".

Make sure "POP" is selected. Under "Incoming Server", type "". Under "Outgoing Server", type "".

Under "Incoming User Name" and "Outgoing User Name", type your Yahoo! ID. This is your email address without the "". Click "Next".

Give your account a descriptive name under "Account Name", such as "Yahoo! Mail". Click "Next" and then "Finish".

Click "Edit" from the SeaMonkey menu and select "Mail & Newsgroup Account Settings".

Click "Server Settings" under your Yahoo! Mail account and make sure "Connection Security" is set to "SSL/TLS".

Click "Outgoing Server (SMTP)". Select your Yahoo! Mail account, then press "Edit". Make sure "Port" is set to 25 and that "Connection Security" is set to "SSL/TLS", then click "OK" to save your settings.


If you are having trouble sending mail, try changing the "Port" setting in Step 9 to "587".
