When using a client like Zoho mail to access your email, should you have POP and IMAP active at the same time?
No, it is not recommended to have both POP (Post Office Protocol) and IMAP (Internet Message Access Protocol) active at the same time when using an email client like Zoho Mail.

POP and IMAP are two different protocols used for retrieving email from a server. Having both active at the same time can lead to issues with duplicates or conflicting information between the email client and server.

It is best to choose one of the two protocols based on your email needs and use it exclusively. For example, if you want to access your email from multiple devices, IMAP would be a better choice, as it syncs the email across all devices. If you prefer to keep a copy of your email on your device, POP would be a better choice, as it downloads a copy of the email to your device.
What about SMTP?
