With programs like Apple Mail, you can send and receive emails on your computer without having to access Webmail.
In this article, we'll show you how to set up your IONOS email account in Apple Mail under macOS with SSL encryption enabled.
macOS Sierra and later provide support for encryption using SSL/TLS. If you are using an older operating system, you may not be able to establish a connection to our email servers to send and receive emails.
Quick Start Guide
If you have not yet set up an email account in Apple Mail:
The Choose a Mail Account Provider window opens.
- Select Other Mail account... and click continue.
If you have already set up an email account in Apple Mail:
Open Mail and click Mail > Add Account ... on the menu bar.
- Select Other Mail Account ....
Use the following settings/information to set up your email account:
|Name||The name displayed on outgoing emails|
|Email address||The full email address you want to set up in Apple Mail. For example: email@example.com|
|Username||The email address you used above. For example: firstname.lastname@example.org|
|Password||The password you have set for your email address.|
|Server for incoming emails||imap.ionos.com|
|IMAP port, SSL enabled||993|
|Server for outgoing emails||smtp.ionos.com|
|SMTP port, SSL enabled||587|
Adding an Email Account to Apple Mail
- Open Apple Mail and click Mail > Add Account... on the menu bar.
- Select the Other mail account... option and click Continue.
- Enter your name, IONOS email address, and password and click Log In. (If you have lost the password to your email account, you can set a new password).
- Under Username, enter your email address again.
Select the desired account type. You can choose between the account types IMAP or POP3. We recommend using the default IMAP setting.
- If you have set the account type to IMAP, enter imap.ionos.com in the Server for incoming email field.
- If you have set the account type to POP3, enter pop.ionos.com in the Server for incoming email field.
- In the Outgoing mail server field, enter smtp.ionos.com and click Log in.
Please note: If the message Account name/Password could not be verified is displayed, please check your entries for completeness/accuracy.
- Select the apps you want to use with your account and click Done.
Enabling SSL Encryption
- On the Mail menu bar, click Mail > Settings.
Click Accounts > Server Settings tab.
Under Incoming email server (IMAP) or Incoming email server (POP3), disable the Manage connection settings automatically option.
Enter the following port number:
- If you have set the account type to IMAP, enter the port number 993 in the Incoming Mail Server (IMAP) > Port field.
- If you have set the account type to POP3, enter the port number 995 in the Incoming Mail Server (POP3) > Port field.
Please note: The TLS/SSL setting allows your emails to be transmitted using SSL encryption as well.
In the Outgoing Mail Server (SMTP) section, disable the Manage connection settings automatically option.
Enter the port number 587 in the Outgoing Mail Server (SMTP) > Port field.
Specifying the Path Prefix for IMAP
To tell Apple Mail the location of your IONOS mailboxes on the IMAP server:
From macOS Sierra 10.12.6 and later:
- Open the Mail app on your Mac.
- Click on Mail > Settings > Accounts tab > Server Settings tab.
- Click the Advanced IMAP Settings button in the Incoming Email Service (IMAP) field.
- Enter the value INBOX in the IMAP path prefix field and finish your entry with OK.
Setting Default Mailboxes in the Mail App
Apple Mail uses six default mailboxes in an email account: Inbox, Spam, Sent, Drafts, Archive, and Trash. Use the mailbox behavior settings to control which mailboxes and where - on the mail server or locally - are used for this purpose.
If you use an IMAP mailbox on a mail server, you can access it from any device on which you have set up the email account. If you are using a local mailbox, you can only access it on this machine.
To manage the default mailboxes for versions macOS Sierra 10.12.6 and later:
- Open the Mail app on your Mac.
- Click Mail > Settings > Accounts tab > Mailbox Behavior tab.
- Select the desired email account in the left sidebar.
- Use the list boxes to set the desired destination mailbox.
Optional: For Spam and Deleted Mails, change the period after which the folder contents are deleted.
