is it possible to have immutable email?
email that might be moved around but can never be deleted from imap/pop3?


please, explain your issue/aim, not your solution, thank you

i’m sorry i dont know how to explain more clearer.

i want to have all my email archived forever on the server and never gets deleted by email client (mua).

You need as special software to meet your needs.

Take a look at:

as giacomo said, you need an external sw… what you’re asking for can’t be done with “email” stack

unfortunately (I’ve tested many solutions like mailpiler and enkive) the mail offline archiving is a business and so there aren’t so many free full featured solutions
