"A non-empty reference name argument is the name of a mailbox or a level of mailbox hierarchy, and indicates the context in which the mailbox name is interpreted."

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 understand what is happening here.

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-l... 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 "/"

Nowadays the LIST reference parameter really shouldn't be anything except empty. It's always IMAP server specific how the parameter is handled.

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?
