1. What's the difference between IMAP and SMTP?

The short answer is that IMAP connects to your email providers' server and is used for receiving email while SMTP is used for sending mail to other servers.

IMAP (Internet Message Access Protocol) is a protocol that requests that your email provider will save all of your messages and folders onto its own servers. This way, whether you are using an email client or webmail, you will be able to connect to your email account and view anything you have received because it’s always stored on their server.

STMP (Simple Mail Transfer Protocol) is the protocol for sending emails out of your account to other destinations. It enables your email client to connect to the server of your provider to send outgoing mail, especially to other servers.

2. Does Mailbird Support IMAP? / Does Mailbird Support POP3?

Yes. Mailbird uses IMAP or POP3 to connect to most email providers. Mailbird’s technology can detect the server settings automatically when you enter your email address.

If it is unable to detect the settings, you can set up your email manually by entering the details your provider has listed for their server settings: like the IMAP or POP3 Port and IMAP or POP3 Security.

You will also need to enter the username and password you have assigned with your email provider.

3. What does 'port' mean in my email settings?

You can think of the 'port' like an address number. The same way that an IP address identifies the location of a computer, the port identifies the application operating on that computer.

There are a few common port numbers, always use the recommended settings to configure your email server to Mailbird.

4. How do I know if I need POP3 or IMAP?

If it is important to you to save space on your desktop, or if you’re worried about backing up your emails, select IMAP. This means that your emails will be stored on the server of your email provider.

POP3 will download your emails to be stored locally and then delete them from the server. This will free up space on your server, but if anything happens to your local storage, those emails won’t be available online. If you are comfortable exclusively having a local copy of your files, POP3 is a viable option.
