Hi Michael,

Geronimo JavaMail hard defaults to / separator. If the separator is manually set to undefined it automatically calculates the separator correctly.

However neither through JavaMail or by command line does
LIST "." "*"
or
LIST . "*"
produce any root listing of default folder on my Dovecot installation.

Only
LIST "" "*"
produces a listing.

Could there be something else wrong in the configuration to cause this?

If Dovecot is using "." as the separator in the base level of hierarchy, then it 
correctly is returning nothing for 'LIST / "*"' - since no mailboxes in Dovecot live 
under that base level of hierarchy.

Gmail returns data because it is using "/" as a separator.

If you want Dovecot to return LIST entries for 'LIST "/" "*"', then configure the base namespace to use 
"/" as a separator.  Of course then 'LIST "." "*"' would return nothing...

Thanks Michael.  I have forwarded that link to the Geronimo JavaMail
team in case they think of anything their end.

But in the documentation you sent it seems that Dovecot should respond
in the case of
LIST / "*"
if my understanding is correct

Is there any way to adjust this behaviour in the settings?  I am
struggling to search for a solution to the problem given the limited
information.

You probably want to read the description of "reference name argument" to

Hi,

i am using dovecot-2.2.10-7.el7.x86_64 on
centos-release-7-3.1611.el7.centos.x86_64.

if i follow this tutorial
https://delog.wordpress.com/2011/05/10/access-imap-server-from-the-command-line-using-openssl/
i can login to my server and successfully list the folders using
tag LIST "" "*"

*   LIST (\HasNoChildren) "." INBOX
tag OK List completed.

no folders are listed using
tag LIST / "*"
tag OK List completed.

when i request a folder listing using JavaMail it similarly sends the
following command and no folders are listed
a97 LIST / "*"
a97 OK List completed.

if i follow the tutorial again and use my gmail account instead of my
dovecot installation i can successfully list folders using both methods
tag LIST / "*"

*   LIST (\HasNoChildren) "/" "youtube"
tag OK List completed.

is there some way to make dovecot list folders when it receives the command
LIST / "*"

i note that in the listings my dovecot installation has "." in the
middle and gmail has a "/"
