youre right difficult to say , might ask some developer of mail clients
this option exists since ever in most pop3 clients, and was wide used
before imap comes more public known

i only know for getmail, getmail is building a list about what allready
downloaded via pop3 so it should be independent whatever the server
reports, no idea how its done by thunderbird etc, perhaps some stuff
with date of mails, or hash comparing...

thunderbirds default on pop3 is leave copy on the server for 14 days
also there is an option for delete mails at once , when they are deleted
from inbox to trash of the pop3 local account trash

where you have the option to use one local pop3 box for all accounts
or use seperate for each account ( some pseudo virtual config )
