===== Glossary =====
 
 //This page is provides a glossary of terms frequently used in phpList. Feel free to add a term you think may be useful to other users.//

~-**Attachment repository** - The "attachment repository" is a directory phplist needs for storing the attachments sent with list messages. The location of the attachment repository  is defined in the configuration file (config.php) through the ''$attachment_repository'' setting.
~-**Backend** - The back-end of phpList refers to the //administrators interface//, i.e., all the pages viewable only by administrators (with the various functions: user, messages, system, etc.).
~-**Batch processing** - Batch processing of messages refers to sending portions of the total number of messages within a specified time frame. If you are on a shared host, it will probably be appreciated if you don't send  out loads of emails in one go. Some shared hosts may even have put a limit to the number of messages you may send per hour or per day. To address these limits you can configure batch processing in your config.php file, through the ''MAILQUEUE_BATCH_SIZE'' and ''MAILQUEUE_BATCH_PERIOD'' settings. See PhpListConfigSendRate
~-**Blacklist** - The Blacklist, or 'blocking list', is a list of all users that unsubscribed. When a user unsubscribes from all lists, his/her email address is automatically placed on the 'blacklist' in order to make sure you never send them any message again in the future.
~-**Frontend** - The front-end of phpList refers to all the pages viewable by the public (such as subscribe page, preferences page, etc.), as opposed to the administrators (such as attributes, send a message, etc.).
~-**Template** - usually refers to [[TemplatesInfo message template]] in the context of phpList. 
~-**Throttle** - Throttle refers to the send speed setting of phpList. To be more precise, it refers to a small delay between each sent message, in order to slow down the send speed and thus avoid overloading the server. Throttle can be configured through the ''MAILQUEUE_THROTTLE'' or the ''MAILQUEUE_AUTOTHROTTLE'' setting in config.php. See PhpListConfigSendRate
