Tere.
It may be the POP3 that's different. Our users were keeping the mail local. Also, I didn't create the folders first, I just dragged the existing ones.
Same here. Mail are keeped in local.
Can you try copying the mails to local folders, then moving them to the IMAP server?
You see, I can copy the mails, but I can't copy the folders, I must create each pop3 subfolder in imap account by hand and then drag & drop pop3 subfolder mails into imap subfolder.
I'm assuming you don't have access to the existing POP3 mail store, or it's not in a format that Dovecot understands, because then you could just point Dovecot at it and go.
I have administator access into desktop and server.
Don't know about the settings though - I assume you mean filters and sorting?
Yes.
No, this was a write-off, because pretty much nobody stores these in the same format.
Ok.
