UTF7 mailbox codification error

Tue Feb 28 10:33:07 EST 2012

Hello,

any news about this "issue"? The only way it works in my environment is "delete" the lines tan set_unicode_folders in IMAPTalk source code.

Thanks!

Hello,

I've made some test trying to check all cases and the results are:

Case 1 OK

Case 2, it fails because set unicode folder is turned off.

Case 3, we can see that once the folder name is passed to the method it change the name and add a "-" after the "&". Thats why the folder does not exist.

Case 4, looks like is the correct way to do it, as when I turn off "unicode_folders" folder name is not modified and internally It works OK, but I get the exception or error that you can see (the same that in case 2)

It looks like set unicode folder has be turned on.

On the other hand, I've installed IMAPTalk from "cpan" and I have 2.01 version.
#perldoc perllocal
PERLLOCAL(1)          User Contributed Perl Documentation         PERLLOCAL(1)

   Thu Feb 23 19:38:12 2012: "Module" Mail::IMAPTalk
       Â·   "installed into: /usr/local/share/perl5"

       Â·   "LINKTYPE: dynamic"

       Â·   "VERSION: 2.01"

       Â·   "EXE_FILES: "

I guess is the same version that you named on the mail, am I right? or I should install other version.

Sorry if my english is not quite correct.

Thanks & Regards.
