Anybody seen this before? Seems easy to reproduce...

I'm using the doveadm import command to extract mails from my backup:

% doveadm import -u restore@backup.invalid mdbox:/home/copymail/mdbox ""
mailbox INBOX header Delivered-To backup+$SEARCHPATTERN@backup.invalid

This works like a charm, I'm getting all the mails, and I can access the newly generated mailbox.

But when executing the command I'm getting an annoying warning:

doveadm(restore@backup.invalid): Error: chdir(/root/) failed: Permission denied (euid=1001(copymail) egid=1001(copymail) missing +x perm: /root, dir owned by 0:0 mode=0700) doveadm(restore@backup.invalid): Error: chdir(/root) failed: Permission denied

Same happened to me. It seems doveadm is changing uids and then chdirs to the original home directory.

I made it go away by using "sudo". This will not fit all situations.

Just guessing…

The signature of the command is: doveadm [-Dv] import [-S socket_path] [-s] -u user source_location dest_parent search_query

You supply "" as dest_parent which I guess could mean ".", and that may be "/root" when run as root. Try "INBOX" or "restore_folder" and see if the error vanishes.

With "INBOX", nothing changes on the output (although the script doesn't restore properly anymore)

With ".", I get:

doveadm(restore@backup.invalid): Error: chdir(/root/) failed: Permission denied (euid=1001(theid) egid=1001(theid) missing +x perm: /root, dir owned by 0:0 mode=0700) doveadm(restore@backup.invalid): Error: chdir(/root) failed: Permission denied doveadm(restore@backup.invalid): Error: Couldn't create mailbox ./INBOX: Invalid mailbox name: Contains '.' part

I still think this is an obscure bug :)

It uses the bash environment variable $HOME instead of

I think there are two independent errors. First: the users home information as shown by doveadm user.

Why do I think so, because if I manually export the bash environment HOME to the Home Directory of the user I want to import to I don't receive this error anymore.

Example: export HOME="/mailhome/userA" doveadm import -u userA maildir:/backup/userA Backup ALL; -> No Error export HOME="/root" doveadm import -u userA maildir:/backup/userA Backup ALL; -> Error as seen above.

Yes, this was my actual problem. So doveadm is really doing something wrong.

Second: That was not my original problem :)

If the first error is a bug or a feature I don't know, but doveadm import works correct with or without this error shown. At least for the things I have done.

Yes, it works. But personally I think it shouldn't emit errors if everything works as expected...

I'll just work around it.
