Sort by Threads rationale

[Ralf Hildebrandt]

I'm using "thread-sort" in mutt, and some people I know use it in
their regular mailreader.

It exists in SquirrelMail as well, but what is the rationale behind this?


Squirrelmail doesn't have a "jump to next unread message", which makes it
impossible to find the unread, new messages in a mailbox that's threaded.

My users are profoundly irritated by this sorting method, especially
when they activate it accidentially.

How can I turn this off permanently?

config/config.php:

Look for allow_thread_sort and allow_server_sort.  We use multilogin
plugin to turn these off selectively.

i'm using mutt with:

set sort                = threads
set sort_aux            = last-date-received

man muttrc:

sort_aux
 Type: sort order
 Default: date

When sorting by threads, this variable controls how threads are sorted in
relation to other threads, and how the  branches  of  the  thread trees  are
sorted.   This  can be set to any value that “$sort” can, except threads (in
that case, mutt will just use date-sent).  You can also specify the last-
prefix in addition to the reverse- prefix, but last- must come after reverse-.
The last- prefix causes messages  to be  sorted  against  its  siblings  by
which  has  the  last  descendant,  using  the  rest of sort_aux as an
ordering.  For instance, set sort_aux=last-date-received would mean that if a
new message is received in a thread, that thread becomes the last one displayed
(or  the first, if you have set sort=reverse-threads.) Note: For reversed
“$sort” order $sort_aux is reversed again (which is not the right thing to do,
but kept to not break any existing configuration setting).


can i use squirrelmail sorting similar to last-date-received ???

SquirrelMail itself doesn't do the sorting/threading, the IMAP server
does.  Unfortunately the spec for the threading does not allow for
anything more than what you want to thread by.

  http://tools.ietf.org/html/rfc5256

So you get to pick subject (pretty obvious what that does), or
references.  References are based on the headers in the email
In-Reply-To, and References.  It does not allow for us to pick date
sorting.

In theory, it would be possible to do two sets of selects.  One to get
the threading order, and another to get the date/time of the email,
then reorder the threads.  That's likely to be rather complex set of
code to go through and reorder everything.
