Android Question POP3: how to check only new emails ?

[juanjo3691]

Hello, when i check my emails i can see an email data with the POP_DownloadCompleted function. Into this function we can check the email with this code:

    Dim m As Message
m = MailParser.ParseMail(Message, File.DirRootExternal)
Dim m_subjet As String = m.Subject

But where or how can i know if an email is new, it has not been open yet. ?

Thanks to all.

you need to remember the message-IDs for later.
Get the list, store the IDs.

Later check mail. Compare the list of mails with the stored IDs.
All mails with an unknown ID are new

Thanks, DonManfred ... First i thought that when we read an email this information (an email has been read or not) is stored in the server.
I need to store this information locally.
Thanks.

It is not a gmail account. Is a personal web adress, like 'www. ... .com'.
Thanks rboek.
