Thunderbird for Mac
Sending and receiving email with Thunderbird Mail for Mac OS X
Mozilla Thunderbird is a fully featured, secure and very functional email client. Here we use "firstname.lastname@example.org" as an example to configure this email client.
Step 1: Add an email account
After opening Thunderbird, click "Email". A window will show up to ask if you would like a new email account. Choose "Skip this and use my existing mail".
In the following window, choose a name for your account, which would be the name that people see when they receive email from you. Here we will just use "Test". Then put your email address as the user name and the password you that setup for this account.
Step 2: Setup incoming and outgoing mail server
As you continue, you will see this window asking for incoming and outgoing mail server info. For IMAP account, choose type as "IMAP" and use imap.dynu.com as incoming mail server. Use IMAP SSL port 993. The authentication method is " Normal password ".
Use smtp.dynu.com as outgoing mail server. Use SMTP SSL port 465. The authentication method is " Normal password".
Step 3: Verify account information
Now you can see your account on the left side of the email client interface. You just need to verify one last time the account information, particularly the information of incoming server and outgoing server.
Right click your email account(in this case, email@example.com), and choose Settings tab, "Account settings" window will show up.
Click on Server Settings, and make sure that IMAP server is imap.dynu.com port is 993.
Click on Outgoing Server(SMTP) tab, verify the information of SMTP outgoing server. Make sure that SMTP server is smtp.dynu.com port is 465.
Now we will be able to send and receive email using firstname.lastname@example.org.
NOTE: If you are using POP3 protocol, please change the incoming server address to pop.dynu.com, and POP SSL port 995. If you are using non SSL port, please refer here for port information.
