I can't find Juno IMAP settings
Juno has no IMAP. It only lists POP (pop.juno.com) and sending (smtp.juno.com), so mail will not stay in sync between devices.
Juno Email: Settings, Sign-In & Fixes
Juno offers POP only, with no IMAP, so a phone and a computer will not stay in sync. Juno pages also disagree on whether free accounts can use a mail program at all.

Juno email server settings
| Server | Address | Port | Security |
|---|---|---|---|
| Incoming (POP) | pop.juno.com | 995 | SSL/TLS |
| Outgoing (SMTP) | smtp.juno.com | 465 | SSL/TLS |
- Username: Your full Juno address (memberid@juno.com)
- Password: No app password: use your Juno password. Using a mail program may need MegaMail or another paid Juno plan; one Juno page says so and another says every member can.
- Use IMAP if you read mail on more than one device; POP downloads mail to one device only.

Common Juno email problems
My mail app won't connect to my free Juno account
Mail program access may need MegaMail or a paid plan. Use webmail.juno.com, or check what your plan includes.
I can't send when I'm on another internet connection
Turn on SSL and outgoing authentication: smtp.juno.com, port 465, SSL on.
My email with a large attachment bounced
Free accounts can send up to 10 MB per message (20 MB on Platinum). Send big files as a link instead.
My mailbox is full
Free mailboxes hold 1 GB (2 GB on Platinum or MegaMail). Delete or download old mail to make room.
Problems that look the same on every provider
Can't sign in, or the password stopped working
- Sign in on the provider's own webmail page first. If that works, the problem is your mail app, not the account.
- If webmail rejects the password, use the provider's "Forgot password" page. Never use a reset link from an email you did not ask for.
- Many providers now need a separate app password (or their own sign-in screen) for Outlook, Apple Mail and phone apps. Your normal password will not work there.
Not receiving emails
- Check Spam, Junk and any filters or "blocked senders" in webmail.
- Check whether the mailbox is full; most providers stop accepting mail at the storage limit.
- If your app shows nothing new but webmail does, remove and re-add the account in the app using IMAP.
Can't send, or emails are stuck in the Outbox
- Check the outgoing (SMTP) server, port and security on this page against your app; old guides often list ports that no longer work.
- Turn on "My outgoing server requires authentication" and use the same username and password as incoming.
- Large attachments are a common cause. Remove the attachment and try again.
Contacts are getting spam from my address
- Change the password from webmail, then sign out of all other sessions if the provider offers it.
- Check forwarding rules, filters and the reply-to address in settings; attackers often add a hidden forward.
- Turn on two-step verification, and update the password anywhere else you used the same one.
Setting it up on a new phone or computer
- Use IMAP rather than POP so mail stays in sync across your phone, computer and webmail.
- Enter your full email address as the username unless the provider says otherwise.
- If the app offers the provider by name (Yahoo, Google, Outlook), choose that instead of "Other".
