3. _C_h_a_n_g_e_s__a_n_d__A_d_d_i_t_i_o_n_s
This chapter lists the changes and additions made to
MediaMail since the 3.2 release.
3.1 _S_e_n_d_i_n_g__L_a_r_g_e__M_e_s_a_g_e_s
Sending very large messages or messages with large
attachments, such as movies or 3D models, is now better
supported by MediaMail. Some mail systems can not receive
these large messages. MediaMail now allows you to send large
messages splitting them into pieces of approximately 250 K,
by default. If the recipient uses MediaMail the pieces will
be reassembled once they are delivered. Note, Other MIME-
compliant mail programs may also provide this reassembly
feature. Message splitting options are controlled by the
variables _s_p_l_i_t__s_i_z_e, _s_p_l_i_t__l_i_m_i_t, and the _s_p_l_i_t__s_e_n_d option
to the _v_e_r_i_f_y variable.
+o The _s_p_l_i_t__l_i_m_i_t variable controls when MediaMail gives
you the option to split the message. A dialog is posted
when the size of the attachment exceeds the variable's
minimum size setting. The variable is set to 250 K by
default. The dialog allows you to choose to split the
message or send it whole.
+o The _s_p_l_i_t__s_i_z_e variable controls the size of each
message part. The variable is set to 250 by default.
+o The _s_p_l_i_t__s_e_n_d_m_a_i_l variable specifies the name of a
script that hands the message parts to sendmail for
delivery.
+o The _s_p_l_i_t__s_e_n_d option of the _v_e_r_i_f_y variable, when set,
posts a the dialog asking you to confirm that you want
to split the message in pieces. If you unset this
option, MediaMail automatically splits the large
message without posting the dialog. Note, if you have
previously customized the _v_e_r_i_f_y variable, this option
will not be set by default.
3.2 _R_e_c_e_i_v_i_n_g__S_p_l_i_t__M_e_s_a_g_e_s
Some systems are not configured to receive messages that
exceed a particular size limit, so a very large message may
be sent in several smaller pieces. MediaMail now reassembles
messages which have been split into pieces as the pieces
arrive on your system. When the pieces of a large message
begin arrivving, you receive a notification message. The
notification message has an attachment that you may use to
check the status of the incoming pieces. Once all the pieces
- 2 -
have arrived, they are reassembled and the entire large
message is delivered to your mailbox. Note, attachments
contained in reassembled messages behave slightly
differently than other attachments. In particular, the
attachments are occupying space on your hard disk, in your
~/Mail/detach.dir directory. If you delete the message, the
attachments will not be automatically deleted and will
continue to take up space on your disk. To delete them, open
a directory view of your ~/Mail/detach.dir directory and
drag the large files to the dumpster. MediaMail reassembles
messages by using a .forward file in your home directory.
Refer to MediaMail online help for more information on the
.forward file.
3.3 _I_n_t_e_r_n_a_t_i_o_n_a_l_i_z_a_t_i_o_n
