Hello I'm using squirrelmail 1.4.8-1, with dovecot 1.0.rc7-1 on a Debian etch system. On the squirrelmail-configure (config.pl), section "General Option", I've enabled "Allow server thread sort" and "Allow server-side sorting". In my account it works, but there is a user that it doesn't work. When she selects the option to sort by subject, she gets the message: Erro: Pedido errado ou mal formado. Requisição: THREAD ORDEREDSUBJECT ISO-8859-1 ALL Resposta do servidor: Error in IMAP command UID: ORDEREDSUBJECT threading is currently not supported. (Sorry the messages are in Portuguese, but i believe that you can get the general idea). I've snooped arround and found that if i change "thread_INBOX=1" in her .pref file to "thread_INBOX=0", then she stops seeing the error. I've tried with my .pref file and if the value is 1 it still works, I've checked and there are other users with the setting to 1 and they can see their mail, so my guess is that something is terribly wrong in the preferences of this particular user, so I'm sending it to you so that maybe you can see something: chosen_theme=../themes/default_theme.php show_html_default=0 javascript_on=0 hililist=a:0:{} sort=6 javascript_setting=0 delete_move_next_t=off delete_move_next_formATtop=off delete_move_next_b=on delete_move_next_formATbottom=on archivefilenames=6 archiveattachments=1 archivetype=0 archiveent=1 spamcop_method=web_form thread_INBOX=0 order1=1 order2=2 order3=5 order4=3 order5=4 show_full_date=0 include_self_reply_all=0 attachment_common_show_images=1 html_mail_aggressive_reply_with_unsafe_images=0 html_mail_aggressive_reply=0 compose_window_type=html pf_cleandisplay=0 sort_by_ref=0 quicksave_frequency=1 quicksave_units=seconds quicksave_encryption=none internal_date_sort=1 select_range_multiple_gaps=top_down Thanks ------------------------------------------------------------------------- Take Surveys.
