I set-up some spam/ham learning folders where a crontab entry learns
the mail and them moves it do a different Maildir folder.
Unfortunately, since it has a different dovecot-keywords file, any imap
flags get changed to unknown-0, unknown-1 etc.
I tried the following, but it didn't work
mv "${src_ham}"/cur/* "$dest_ham"/new/
cp "${src_ham}"/dovecot-keywords "${dest_ham}"
Is there a simple way to do this correctly without going through IMAP?
And are there any more serious consequences of moving mail like this,
with dovecot imap running on top.
