Runbox SMTP Settings
You must first configure an email client setup for SMTP (Simple Mail Transfer Protocol) to send outgoing messages via the Runbox servers.
Below are the SMTP settings:
| Option | Description |
|---|---|
| SMTP Host: | mail.runbox.com |
| SMTP Port: | 465 TLS/SSL or 587 STARTTLS |
| SMTP Username: | username@runbox.com or just username |
| SMTP Password: | Your email account password |
Runbox Mail Settings For Receiving Emails
IMAP synchronizes all emails on the server with your client, which means that you can read all your messages on many different devices, whereas POP allows you to download your emails without storing them on the Runbox servers.
Below are the POP and IMAP settings, respectively:
Runbox Email POP Settings
| Option | Description |
|---|---|
| POP3 Host: | mail.runbox.com |
| POP3 Port: | 995 |
| Requires SSL: | Yes |
| POP3 Username: | username@runbox.com or just username |
| POP3 Password: | Your email account password |
Runbox Email IMAP Settings
| Option | Description |
|---|---|
| IMAP Host: | mail.runbox.com |
| IMAP Port: | 993 |
| Requires SSL: | Yes |
| IMAP Username: | username@runbox.com or just username |
| IMAP Password: | Your email account password |
Useful Information to Remember
Aside from the email settings, here is another point to consider about using usernames.
Your username and password are required to access the email servers, for starters.
When logged in to your Runbox webmail, your username gets shown above your email list at the upper right. Your username also appears on the account page and the folder list.
Remember, you cannot use the alias addresses to log in.
Notably, other Runbox domains include @runbox.no, rbx.run, rbx.email, offshore.rocks, and mailhouse.biz. Moreover, under Account → Aliases, you can find a complete list of alternative synonym domains for more options.
Your username may not have changed if you added your domain after receiving a @runbox address, even if you use your domain to send emails. To be doubly sure, check your username in the Runbox webmail.
💡 Tip: Port 465 may be more secure than port 587. In other circumstances, though, port 587 may be more compatible with more mail programs.

IMAP or POP3: What is the Difference?
When configuring a mailbox in an email client, you must determine whether you want to use POP3 or IMAP as the delivery method.
Both platforms can connect to a mail server so that you may read your emails through a mail client such as Outlook or Thunderbird. However, there are certain distinctions between them.
To begin, IMAP stands for Internet Message Access Protocol. Essentially, using IMAP, the message does not stay on the local device, such as a computer, but instead remains on the server itself.
POP3, on the other hand, is an abbreviation for Post Office Protocol. POP3 mail will connect to the server and attempt to keep the message on a local device such as a computer or mobile.
In the end, IMAP is preferable if you intend to access your mailbox from a variety of devices, including a work computer and a smartphone; POP3 is more efficient if you only have one device but have a large number of emails.
However, for most individuals, IMAP remains the protocol of choice.
