I got fed up with the email service which came with my domains and, not wanting to run my own email server, I ended up signing up with fastmail. Anyway, it's a pretty nice service, imap and all, but I have all this old email accumulated in pocomail over the years which I would love to bring forward.
Alas nobody managed to get pocomail to connect to fastmail. Thankfully the mailboxes are in a standard format so can be imported in almost any client i have ever seen... so i need another imap client which lets me move my old mail to imap.
I tried thunderbird last summer, and didn't have much luck - i imported my old email in tb, set up the imap and tried drag-n-drop to move the local messages on to imap. It seems I have to do it one message at a time and the date of the message becomes the date of the upload, not the original date.
I tried opera and I can do multiple messages with it, but the date is skewed too.
At this stage I don't know whether the date thing is a limitation of the software or the imap server at my provider.
Before I download and test 5 different imap clients, I wondered if those of you using newer versions of TB and other email clients could let me know if their tool lets them move multiple emails to the imap mailboxes and does so preserving the original dates?
