doveadm 备份不会从根 INBOX 传输邮件

  • 772

我正在尝试将 IMAP 邮件从 dovecot 1.1.20apple0.5 (osx) 迁移到 dovecot 2.2.33.2 (ubuntu)。我正在使用“doveadm 备份”来迁移我的数据。它适用于所有子文件夹，但根 INBOX 在新服务器上保持为空。我怀疑与层次分隔符（以前的服务器上的“.”，新服务器上的“/”）或命名空间前缀（新服务器上的设置为“INBOX/”）有关的问题。有什么提示吗？

显示收件箱中没有消息：

# doveadm mailbox status -u (myuser) all INBOX
INBOX messages=0 recent=0 uidnext=1 uidvalidity=1553630060 unseen=0 highestmodseq=1 vsize=0 guid=d54cd42849739b5cb5790000ed87e144 firstsaved=18446744073709551615

显示子目录中有消息：

# doveadm mailbox status -u (myuser) all INBOX/Sent
INBOX/Sent messages=253 recent=0 uidnext=8721 uidvalidity=1263328366 unseen=0 highestmodseq=256 vsize=16335358 guid=bfb2e03fdce327671e82bf173b1ccb8b firstsaved=1553634631

我在新服务器上运行的用于迁移数据的命令：

# doveadm -o mail_fsync=never backup -R -u (myuser) imapc:

我在新服务器上的配置：

# doveadm -n
# 2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.21 (92477967)

    我没有找到如何使 doveadm 备份/同步正常工作，但我在 imapsync 上取得了成功。它慢得多，但它的工作原理！
