We're hoping we can get some of the speed issues resolved, and in
fact the development series is faster in some areas that stable.

Forcing a dependency on a system such as MySQL breaks SquirrelMail
away from what it's trying to be, have as few a depencies as
possible.

One of the things I am currently reviewing is the sessioning, and
the extensive use of it. My plans include making it flexible enough
to allow the use of a database storage for the session information
as well as allow the standard usage of session (plain files).

This is what I had planned. I was going to try making a custom
session system of sorts that'd allow integration with most database
types (maybe just use PEAR), or stick with the standard file format
that PHP currently uses.

I am not sure what you are trying to do with this? Could you explain
a little more.

$identity is a value used to set the From field. This is normally
set to 0 unless you have multiple identities setup (see Options ->
Personal Information). I introduced some code that would allow for
the SquirrelMail interface to attempt to pick an identity based on
who the mail was addressed to.

There is certain information stored in the session file when
composing a new email, or a forward. I believe details on the
attachments are stored in this session information, for use in the
sending of the attachment. Have you checked the items created in the
../data/ directory to see if they are really the files you attached,
and that they are not empty? For an experiment, at the bottom of
the src/compose.php file, above the closing of the HTML tags (about
line 841-842), put in the following lines:
echo '<pre>';
print_r($_SESSION);
echo '</pre>';
What you should see then is a large session array containing a lot
of useful information. This is probably about the time you scream
and pull your hair out as you realize how much we use sessions, and
how much stuff probably shouldn't be in there (I'm working on the
review). Scroll down, and check to see if you have an attachments
item, and check to see if it has all the information to the file you
are supposed to be including as your attachment. If you don't, then
the session isn't being set properly, at which point we know where
to start looking.
