Re: [Evolution] options on download

I assume that it remembers the UID of the message? Because the assigned
number to each message obviously changes if the other messages are deleted

Okay, so I understand that much, but a lot of POP providers have messed up
UID system.
How, then, does this work? The only way I see this as being possible
(correct me if I'm wrong) is to download the header again and check the
"Message-Id" header field, is this the way Netscape does/did it?

And then, at this point, I assume that the message should be downloaded via
RETR and then overwrite the partial message in the mbox file?

I'm not 100% sure how Netscape saves it's messages, but this might not
easily work in an mbox file, in something like MH it would be easy though
(doesn't that format have a separate file for each message? or am I
thinking of a different format?)
