If we've moved your office's email domain to our new Zimbra platform, you will need to make some settings changes within your email client in order to be able to Send and Receive email. For a brief post just highlighting the settings themself, which would apply to whatever email client you are using, please see this post. Here, I'm going to go over making those changes in Mail (Mac).
If you already had your email account set up within Mail, and it was set up as an IMAP account, we do recommend that you delete the account and add it as a new email account. If you previously had it set up as a POP account, you can just edit the existing account with the new server information.
To delete an existing account within Mail (recommended if currently set up as an IMAP account), go to Mail's Preferences:
Go to the Accounts tab, click the email account you want to delete, then click the minus icon at the bottom to delete the account:
You'll then be asked to confirm the deletion. After doing so, you can proceed to adding the account back with your new server settings.
Add IMAP account with new settings
After deleting your IMAP account, you're now ready to add it back. Just click on the plus icon to the left of the minus icon (see screenshot above.) Or, under Mail's File menu, click Add Account. You'll then see the below:
Enter your Full Name (this will be used in outgoing messages), Email Address and Email Password and click Continue. You'll see the below as Mail searches for mail servers for your email address:
After this process has run, you will see the below dialog:
Account Type: select IMAP from this menu.
Description: Enter the name of the account. This descriptive name is for your use and appears on some mailboxes and folders in the Mail sidebar.
Incoming Mail Server: enter imap.redtailtechnology.com.
User Name: this will be your full email address.
Password: enter your email password.
If my name were Tucker Smith and my email was email@example.com, this would look like the below:
After entering your information, click Continue. You'll then see the below:
Description: Enter a description of the server. This description is for your use.
Outgoing Mail Server: enter smtp.redtailtechnology.com.
Use only this server: Select this checkbox to use only the specified SMTP server to send mail.
Use Authentication: Select the checkbox to authenticate before sending messages.
User Name: enter your full email address
Password: enter your email password
After entering your information, this might look something like the below:
Then, click Continue. Next, you'll see a dialog for Outgoing Mail Security:
Check off Use Secure Sockets Layer (SSL) - this provides additional security when sending messages to a server.
Choose Password as the Authentication method. Then click Continue. Next, you'll see an Account Summary:
Look this over to make sure all looks correct and then click Create. This will complete the setup of your email as an IMAP account.
Edit Existing POP account with new settings
If your account was previously set up as a POP account, and you want it to remain a POP account, you can just edit some of your existing settings. Go to Mail's Preferences:
On the Accounts tab, click the POP account in question:
You'll then need to change the Incoming Mail Server info for the account so it looks like the below:
As you can see, the Incoming Mail Server should now read pop.redtailtechnology.com. You'll then want to click on the arrows in the box for your Outgoing Mail Server (SMTP) and click Edit SMTP Server List:
You'll see the below:
Replace whatever is in the Server Name box with smtp.redtailtechnology.com. Then, click the Advanced tab. You'll then see:
If not already, check off Use Secure Sockets Layer (SSL) and select Password as the Authentication method. Then click OK. You'll then be back on your Preferences dialog on the Accounts pane. Click the Advanced tab:
On the Advanced Tab, if not already, check off Use SSL and select Password as the Authentication method.
This should complete the necessary changes to your POP settings.
