Critical information here is also what protocol you are using to access
your mail - IMAP or POP (or something else)

That all sounds like correct behaviour for an IMAP connection - and how
it has behaved for many, many years.

That is a POP3 option, not IMAP - with IMAP everything is on the
server, always, and what you see in Evolution mirrors what's on the
server.  With POP3 you download the mail to your local machine and by
default it is then removed from the server - unless you have set "leave
messages on server".

It sounds like you have configured the account to use IMAP when you
really wanted POP. You can check this by going to 

 Edit -> Preferences -> (Account name) -> Edit -> Receiving E-mail

the top line of that page should say "Server Type: IMAP" (or POP)

Also POP mail is delivered into the "On This Computer" INBOX (in the
absence of any filters), IMAP mail will be in a folder tree headed with
the Account Name (usually the email address).
