Connect an External Email Account
You can connect the personal or business mail you use now (Gmail, NAVER Mail, and others) to the SetFN workspace and check it all in one place.
Try using it this way
Company mail, personal mail... Is it a burden to use email in several different places? When you connect external accounts, you can check them all at once in SetFN.
The connection method depends on what you want to do.
When you only want to check email in the SetFN workspace
Connect only POP3. Check new mail in SetFN, and sign in to the original service directly to reply or send a new message.
When you want to send email
Connect SMTP as well. You can handle everything in SetFN, from checking mail to replying and writing new mail. SMTP handles sending only, so to receive in SetFN too, you must also turn on POP3.
Before you begin
- In the settings of the external mail service, turn on POP3 or IMAP, and SMTP.
- To import existing mail, select the range of mail to receive in the external mail service.
- Issue the app password used for account authentication in the external mail service.
Open the external mail connection screen
- Select
Emailin the left bar of Workspace. - Select
Settingsat the lower left of the email screen. - On the
Mailboxestab, selectConnect external mail.

Enter the basic information
Email address
In Email address, enter the full address of the external mail account to connect. For example, enter it in the format name@example.com.
When you enter the email address, SetFN detects the mail service. If it is not detected automatically or you need to use different settings, select the mail service yourself.
Sender name
In Sender name, enter the name to show on the recipient's email screen. When you connect with POP3/SMTP, you must enter the sender name yourself.
Mailbox access
Select the scope in which the connected mail is used.
| Option | Description |
|---|---|
P Personal mailbox | Connects it as a mailbox used by an individual. |
T Team mailbox | Connects it as a mailbox used together by multiple users. |
Select a mail service
In Mail service, select the service you use. For major services, the receiving server, the sending server, and the secure ports are entered automatically.
- Gmail
- NAVER
- Daum
- Yahoo!
- iCloud
- Zoho
If the service is not in the list, select Other. If you need settings different from the automatically entered values, check the server settings yourself and enter them.
Set the receiving method
In Receiving method, select how mail is imported.
| Receiving method | Description |
|---|---|
POP3 | Imports mail to the SetFN server and stores it separately. Recommended when you want to collect existing mail as well or reduce the storage used at the external mail service. |
IMAP | Imports only new mail in the inbox and leaves the mail on the external server as it is. Other folders and the read and starred states are not synchronized. |
SMTP | Only sends mail from this address, without receiving. |
When you turn on Delete from the external server after import, mail that has been saved in SetFN is also deleted from the external server. The default is off, and you can turn it on only when the administrator has allowed POP3 remote deletion.
With POP3 and IMAP, the external mail server does not notify SetFN of new mail in real time. Instead, SetFN connects at regular intervals (5 minutes by default; the administrator can adjust it) and checks whether there is new mail. Therefore, mail comes into SetFN at the next check, not immediately when it arrives. To check right away, select Sync now.
Before connecting, check the following items in the external mail service.
- Check that POP3 or IMAP, and SMTP, are turned on.
- To receive existing mail as well with POP3, check that the range to receive is selected.
Send with the external account
To send mail from the external mail address, turn on Send mail from this address. The SMTP sending settings are applied separately from the receiving connection.
If you do not use the sending feature, only external mail receiving is connected. This only means that you cannot send from this external address. If you have a SetFN business mail account, you can send mail from that address as before.
Switch safely
If you want to move to SetFN while keeping the mail service you already use, turning on receiving and sending separately, in order, is recommended.
- Connect only POP3 receiving first. If you leave
Delete from the external server after importoff, the original mail in the external mail service remains as it is, and SetFN receives only copies. You can keep using your existing mail app or webmail as usual. - After you confirm that mail arrives in SetFN correctly, if you also want to send from SetFN, turn on
Send mail from this addressto connect SMTP sending additionally.
From the moment you turn on sending, records of mail sent from this address also start to remain in SetFN, so the safe order is to check the receiving status first and turn on sending later.
Check the server settings
In Server settings, check the receiving server and the selected sending server. When you connect Gmail with POP3, Incoming server is filled with pop.gmail.com and Incoming port with 995.
If you do not want to use the automatically entered servers, change the server address and port under Server settings to the values of the mail service you use.
Authenticate the account
Login ID
In Login ID, enter the ID you use to sign in to the external mail service.
NAVER uses the value before @ in the email address as the default login ID. If your account settings are different, you can edit the login ID.
App password
Enter the app password issued by the external mail service. The app password is entered only when you connect the account.
After you enter all the information, select Verify connection. When the connection is complete, the external mailbox appears in the mailbox list.
Good to Know
- The external mail service may require an app password instead of the regular sign-in password.
- The range of existing mail that can be imported with POP3 depends on the settings of the external mail service.
- The receiving connection and SMTP sending are separate settings, so to send mail, check the sending option and the sending server together.
- When you connect a team mailbox, check the members who will use the mail and the sending permission together.
