Programs such as<CITE>mail</CITE>,<CITE>mailx</CITE>, and<CITE>elm</CITE> store mail foldersas files, each file containing one or more mail messages. Thename of the file is the name of the folder. A line starting with thecharacters "From" is considered the start of a new message.<P>The<CITE>MMDF</CITE> program also stores folders as a single file containingone or more messages. However, in<CITE>MMDF</CITE>-style folders a linecontaining four Ctrl-A characters at the beginning and end ofeach message is used to separate messages.<P>The<CITE>mh</CITE> program, and related tools such as<CITE>xmh</CITE> and<CITE>exmh</CITE>, use adirectory as a mail folder. Mail messages are saved as individualfiles in the directory. The folder name is the directory name, andthe names of the files in the directory are numbers correspondingto the mail message number.<P><CITE>Ishmail</CITE> can work with any of these three mail folder types.<P><CITE>Ishmail's</CITE> ability to share mail files with these other mailprograms gives you the flexibility of accessing your mail foldersvia a "dial-up" modem connection from any remote location. Inmost cases, such dial-up modem connections are throughcharacter-mode mail programs such as<CITE>elm, mh, mail</CITE>, and<CITE>mailx</CITE>.<P>If you intend to use acharacter-mode interface to access yourmail remotely through adial-up connection to the host system onwhich your mail resides, you should save your changes to<CITE>Ishmail</CITE>before using the other mail interface. Otherwise you could loseunsaved changes.<P>You can make changes to your mail folders using another mailinterface program such as<CITE>mail</CITE> or<CITE>mailx</CITE> while<CITE>Ishmail</CITE> issimultaneously running on your host system. If you do, thepotential exists for some mail messages to get out of sync withthe internal copies kept by<CITE>Ishmail</CITE>, possibly resulting in some"Read" messages reverting back to "New" status. Somepreviously deleted messages may also show up again in<CITE>Ishmail</CITE>.<P>As a safeguard against data loss,<CITE>Ishmail</CITE> detects changes in thestatus of open mail folders. The next time you use<CITE>Ishmail</CITE>, it willnotify you with a pop-up window that a folder has been changedby another program. When that happens,<CITE>Ishmail</CITE> always rereadsthe folder file to get the most up-to-date copy. As a result, anychanges you previously made while in<CITE>Ishmail</CITE> but didn't save willbe lost.<HR>Preceding Section: <A HREF="X-7NkEBPyK9X3cS.html">Customizing Ishmail</A><BR>Following Section: <A HREF="QOrBmMB7OM9X3cS.html">Exiting Ishmail</A><BR>Parent Section: <A HREF="A-7NkEBPyK9X3cS.html">Starting Ishmail</A><BR>Contents of <A HREF="zsPsIGBSYWwA0YK.html">Ishmail User's Guide</A><BR><HR></BODY></HTML>⌨️ 快捷键说明
