Mail migration problem

[Germán Herrera]

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!
