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)。我使用“doveadm backup”来迁移我的数据。它对所有子文件夹都运行良好,但新服务器上的根 INBOX 仍为空。我怀疑问题与层次分隔符(以前的服务器上为“。”,新的服务器上为“/”)或命名空间前缀(在新服务器上设置为“INBOX/”)有关。有什么提示吗?
显示收件箱中没有邮件:
# 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:

答案1
我不知道如何让 doveadm 备份/同步正常工作,但我成功使用了 imapsync。它慢得多,但可以工作!
