Re: Mail migration problem

I see, it seems it wasn't compiled with maildir storage engine.

About running another dovecot instance on the same box, I never tried it myself, but I guess you could have your production version (which needs to support maildir, otherwise you won't be able to access the mailboxes after the migration) in /usr (as distros usually do), and install your customized version (with support for maildir and dbox for the migration) in /usr/local.

If you go this way, you will have to reference the dovecot version you're addressing with the full path (/usr/bin/doveadm or /usr/local/bin/doveadm), or you'll have to rely on your $PATH environment variable. You also need to take into account to separate the /etc directories for both instances, because you'll probably need slightly different configurations.

Cheers

Yeah, I think dovecot was a custom compiled build

Version is 2.2.18

and --build-options:

Build options: ioloop=epoll notify=inotify ipv6 openssl io_block_size=8192 Mail storages: shared mdbox raw fail SQL drivers: mysql Passdb: checkpassword pam passwd passwd-file shadow sql Userdb: checkpassword nss passwd prefetch passwd-file sql

At that point my question is if I can run another dovecot build on the same box? I knew I can run the same instance but as is this a custom build I want to have something generic just to use for migration purposes.

Thanks, Adam

Well, judging by the error message it appears like dovecot hasn't 

been compiled with support for maildir, which is strange because I don't see any way to disable in the compile-time options.

Are you using the precompiled package from the distro or compiling
dovecot by yourself? Could you share the output of "dovecot
--build-options" and "dovecot --version"?

Thanks!
