OK, thank you for your answer.
I did a little check in order to understand what are these "SORT" extension
I found rfc 3501 , March 2003. (cfr:
http://www.isi.edu/in-notes/rfc3501.txt)
In this rfc there is nothing about SORT. Moreover, Extension and
experimental commands should start with X letter.
Second: Lotus Domino server (and all IMAP server) has already sorted
messages, using UID
This is the rfc piece talking about UID
A 32-bit value assigned to each message, which when used with the
unique identifier validity value (see below) forms a 64-bit value
that MUST NOT refer to any other message in the mailbox or any
subsequent mailbox with the same name forever. Unique identifiers
are assigned in a strictly ascending fashion in the mailbox; as each
message is added to the mailbox it is assigned a higher UID than the
message(s) which were added previously. Unlike message sequence
numbers, unique identifiers are not necessarily contiguous.
So: I am the last arrived to squrrelmail but I think that, in principle,
squirrelmail should not read all the headers to know which are the last 15
messages !
Anyway, if it was engineered in this way it is not suitable for my needs:
Unfortunately I should continue using the mail internet interface of Lotus
Domino, which does not work on linux platform or mac platform (actually it
works only on Internet Explorer.)
thanks all again,

It needs to read all of the headers (not the full message) in order to
sort them to figure out which 15 to display first.
