How to disable auto sync of emails

[Avishag]

I would like to disable auto sync of emails between my iPhone and my MacBook Pro, so when I delete an email on my iPhone it would not affect my emails in iMail. If possible, what is the way to do so?
Thank you.

They're probably not syncing with each other in the first place. It's likely that they're both syncing with the mail server.

It's difficult to give you an answer without the details. What type of account is it? If you can set it up as POP then set it up as POP and it definitely will not sync.
