Hi!

I'm trying to migrate a mailbox from an old IMAP server (not Dovecot) to a new Dovecot server with 'doveadm backup'. The command fails because of an unexpected character in a mailbox name:


doveadm -o imapc_user=a...@example.org \
        -o imapc_password=XXX \
        -o imapc_host=old-mailserver.webflow.de \
        -o imapc_port=993 \
        -o imapc_ssl=imaps \
        -o imapc_ssl_verify=no \
        -o imapc_features=rfc822.size,fetch-headers \
        -o ssl_client_ca_dir=/etc/ssl \
        backup -R -f -x ~* -u migration...@example.org imapc:

dsync(migration...@example.org): Info: imapc(old-mailserver.webflow.de:993): Connected to 1.1.1.1:993 (local 2.2.2.2:46154) dsync(migration...@example.org): Error: Failed to access mailbox Entw?rfe: mailbox does not exist


The problem is with "Entw?rfe" here. It's actually Entw<0xfc>rfe, which translates to "Entwürfe" in ISO-8859-1.

Why can't doveadm find that mailbox? Is the old mailserver misbehaving (I hope not because I have no idea how to change that...), or does this happen on the new server? Can I tell doveadm something that makes this work?


Thank you

Michael
