[Dovecot] Converting a POP3 client to IMAP
I have a dovecot 2.0 dovecot server set up for https/imap with spam, av, and some preliminary sieve filters in place.
Our current email is outsourced and so we have used POP3 to keep all email on our systems for many years.
I have run tests to move mail to the new imap server and that seems to work pretty well.
However, we have lots of mail going back over a decade and used a lot of aliases that forwarded email to many users. I find the moving mail multiple times using Thunderbird results in multiple copies of the same email.
Is there a best practice for moving mail such that we can take advantage of the hard link feature for all those older copies that are currently in POP3 files?
It would also be nice to be able to auto file things. I don't see the sieve filters being activated when I copy mail in Thunderbird.
Many thanks in advance for any guidance.
Kris

you could use fetchmail to get the messages from the POP3 box and pass them to Dovecot deliver. So you can use Sieve filters (or not, if you turn Sieve off for this).
Then let the messages spool to Maildir.
Then use fdupes to find duplicates and hardlink them.

Hi Steffen, Thank you so much for your quick reply! I apparently missed it the first time.
I think this is close to what I need. My only problem is that all of the mail is currently in a Thunderbird client (we don't leave messages on our current POP3 server).
Could I set up each user with a migration account, so they can drag/drop their email to get them on the mail server (in imap or pop3 if needed?) and then somehow use fetchmail to process the messages again to their new real account (sieve & all)?
Kris

you can drag&drop messages to any IMAP severver or folder in your client, even between different imap servers or from imap to local vice versa
