![]() This is done by using dsync_features setting in config file, such as dsync_features = empty-header-workaround Especially autocreated mailboxes can interfere with migration.ĭsync can be configured with features and workarounds. If you can't use master users, you'll need the users' plaintext passwords and change the appropriate configuration to use them.įor migration, it is recommended to have a separate /etc/dovecot/nf which contains only the settings you need for migration. We'll assume that you can log in with master user "master" that has a password "masteruser-secret". This page describes how to migrate mails to Dovecot from a remote IMAP/POP3 server, preserving the IMAP UIDs, POP3 UIDLs and everything else.
