Daum was South Korea’s original number-two portal, acquired by Kakao in 2014 to form Kakao Corp. Its mail service on the @daum.net and legacy @hanmail.net domains continues under Kakao management. To connect a Daum mailbox to Outlook, Thunderbird, Apple Mail, or a mobile client, use the settings below with your Daum (Kakao) account password.
Daum disables external IMAP/POP3/SMTP by default. Sign in to Daum Mail webmail, open the environment settings, and toggle IMAP/POP3 access ON. If Kakao 2FA is enabled on the parent account, generate a dedicated app password in Kakao security settings; the primary password will not work with IMAP/SMTP. Legacy @hanmail.net addresses use the same daum.net servers. Reference: SMTP 550 5.7.1 guide.
Quick Reference: Daum.net Server Settings
Enable IMAP/POP3 in Daum webmail first. Encryption is required across all three protocols.
| Protocol | Server | Port | Encryption | Authentication |
|---|---|---|---|---|
| SMTP (outgoing, most common) | smtp.daum.net | 465 (SSL) or 587 (STARTTLS) | Required | Full email + password (or app password) |
| IMAP (incoming, recommended) | imap.daum.net | 993 | SSL/TLS | Full email + password (or app password) |
| POP3 (incoming, single device) | pop.daum.net | 995 | SSL/TLS | Full email + password (or app password) |
Daum.net SMTP Settings (Sending Mail)
SMTP handles outbound mail. Server smtp.daum.net on port 465 SSL or 587 STARTTLS. Authentication uses the full user@daum.net (or @hanmail.net) as username and your Daum password (or Kakao-generated app password if 2FA is on).
Daum applies strict rate limits on consumer SMTP, around 500 recipients per day. Above that, sending is throttled with 5.7.x rejection. Newsletters or transactional apps need a dedicated relay.
Daum.net IMAP Settings (Recommended for Reading)
IMAP syncs folder state across every device. Server imap.daum.net on port 993 SSL/TLS. Folder labels appear in Korean in webmail (보λΈνΈμ§ν¨, μμ보κ΄ν¨, ν΄μ§ν΅), but IMAP folder attributes let Outlook, Apple Mail, and Thunderbird map them to Sent, Drafts, and Trash correctly.
Daum.net POP3 Settings (Single-Device Access)
POP3 downloads mail to one device with no server-side sync. Use pop.daum.net on port 995 SSL/TLS. Pick POP3 only if you specifically need offline archival on one device, otherwise IMAP is the correct default.

Frequently Asked Questions
How do I recover a forgotten Daum.net email password?
Since Kakao acquired Daum, recovery goes through the Kakao account system. Sign in at the Daum or Kakao login page, select “Forgot Password”, and verify through the phone number registered on the Kakao account. If 2FA is on, remember to regenerate the IMAP/SMTP app password after reset.
Can I use Daum email on mobile?
Yes, standard IMAP/SMTP with password (or app password if 2FA is on) works in any mobile client. Kakao also publishes a native Daum Mail app that offers OAuth-based login. iOS Mail, Outlook mobile, Gmail app, Thunderbird Mobile all work with the standard settings.
Is Daum.net email free?
Yes. Daum mail is offered as a free service tied to a Kakao account. Both new @daum.net addresses and grandfathered @hanmail.net addresses run on the same infrastructure at no charge.
How do I block spam on Daum email?
Enable spam filters in Daum webmail settings and use the block list to reject known-bad senders. Mark suspicious messages as spam so Daum’s filter improves. Client-side rules (Outlook, Thunderbird) work alongside but only run when the client is open.
What is the Daum mailbox storage limit?
Standard accounts typically get around 10 GB of mailbox storage. Attachment cap is around 25 MB per outbound message. Kakao MyBox integration allows sharing larger files via cloud links. Related: SMTP connection guide.
About This Guide
The Daum.net email settings on this page were last verified on April 12, 2026 against the provider’s official help documentation, publicly available postmaster resources, and independent user setup reports. Email server configurations rarely change once established, most providers issue major updates only every one to two years, typically tied to phasing out unencrypted protocols or migrating to new mail infrastructure. SMTPedia re-verifies these settings quarterly and after any announced changes from Daum.net. If you find a discrepancy between what is documented here and what Daum.net currently requires, please report it so we can update the reference.
