<title>Glossary</title>
<section id="pop">
<title>POP</title>
<p>An acronym for “Post Office Protocol”, a simple method of
retrieving mail messages from a remote mail server. Widely
used by mail clients from an Internet Service Provider's mail
server to a user's machine for viewing. Currently most people
use version three of the protocol, otherwise known as POP3. A
very simple protocol, and not very flexible, but simple to
implement and ubiquitous throughout the internet.</p>
</section>
<section id="imap">
<title>IMAP</title>
<p>An acronym that stands for “Internet Mail Access
Protocol”. It is a newer method of accessing mail over the
internet. It is far more featureful than &POP3;, allowing
for remote folders on the mail server, and more control over
mail delivery. However it is not as widely supported.</p>
</section>
<section id="ldap">
<title>LDAP</title>
<p>An acronym for “Lightweight Directory Access Protocol”. It
is a widely-accepted standard for accessing contact
information over a network. This enables organizations to
store address information in a central database, but have
many people able to access it.</p>
</section>
<section id="libmutt">
<title>libmutt</title>
<p>The library based on Mutt's code and used by previous
versions of &Balsa; to handle local mail and IMAP
servers.</p>
</section>
<section id="mailbox-list">
<title>mailbox list</title>
<p>The list of mailboxes found in &Balsa;'s left hand
pane.</p>
</section>
<section id="message-index">
<title>message index</title>
<p>The list of messages in &Balsa;'s upper-right hand
pane.</p>
</section>
<section id="message-view">
<title>message view</title>
<p>The message display in &Balsa;'s lower-right hand
pane.</p>
</section>
<section id="mda">
<title>MDA</title>
<p>An acronym for “Mail Delivery Agent”, this type of program
is also known as a Local Delivery Agent (LDA). It is
responsible for delivering the mail received for someone on a
machine to the mail folder of that person. &procmail; is
an example of this type of program, although many
<link xref="glossary#mta">MTA</link>'s have their own
MDA implementations.</p>
</section>
<section id="mta">
<title>MTA</title>
<p>An acronym for “Mail Transfer Agent”, this class of
program is responsible for moving mail around between people,
be they on the same computer, or on completely separate
networks. Examples of this type of program include
<app>sendmail</app>,
<app>qmail</app>, and
<app>postfix</app>.</p>
</section>
<section id="mua">
<title>MUA</title>
<p>An acronym for “Mail User Agent”, this is the program a user
would use to read existing mail and create new messages. MUAs
are one of three types of programs that allow internet email
to work. The other two types of programs are
<link xref="glossary#mta">MTA</link>s and
<link xref="glossary#mda">MDA</link>s. &Balsa; is
primarily an MUA, but it also functions as an MDA/MTA when
retrieving mail from a remote server.</p>
</section>
<section id="regular-expression">
<title>Regular Expression</title>
<p>Often abbreviated as a
<em>regexp</em>, this is a method of specifying a pattern to
match in text. Both very simple and very complex patterns can
be easily matched using this method. For information on how
to understand and construct regular expressions the best
source is the
<cmd>grep</cmd> manual or info page.</p>
</section>
<section id="smtp">
<title>SMTP</title>
<p>An acronym that stands for “Simple Mail Transfer
Protocol”, it is exactly that. A standard that defines a
simple and reliable way to transfer messages between computers
on a network. It is used by most, if not all, mail programs
to transfer mail.</p>
</section>
<section id="vcard">
<title>VCARD</title>
<p>VCARD is a standard method of storing contact information
for easy exchange between programs. &Balsa; supports
VCARD addressbooks, as does GnomeCard and Evolution. Many
other programs are capable of exporting their contact lists
in VCARD format as well.</p>
