Apache Commons Net IMAPsClient List Command

Question

I'm trying to connect to www.gmx.net via the apache commons net ImapsClient

I'm able to log in and to fetch messages from folders i know. but my problem is on listing folders.

JavaDoc tells me

boolean list(String refName, String mailboxName) Send a LIST command to the server.

whereat the RFC says send "" "*" to list all folders. so if i call

imap.list("", "*");

the server returns me

AAAB LIST *

AAAB BAD expected 1*ASTRING-CHAR / string instead of " "

[AAAB BAD expected 1*ASTRING-CHAR / string instead of " "]

so if i call

imap.list("/", "*");

the server returns me

AAAB LIST *

AAAB OK LIST completed

[AAAB OK LIST completed]

but no folders get listed. As i can select folders Inbox and Spamverdacht there are obviously more than NO folders.

FULL log of one of this 'empty results' is:

AAAB LIST / *

[AAAB OK LIST completed]

AAAC LOGOUT

• BYE Server logging out

whats my mistake?

Answer 1

Sounds like it doesn't do proper escaping.

Try imap.list("\"\"", "\"*\""), that is put in escaped quotes.
