# pop3front(8)

POP3 Front End

## NAME

pop2front - POP3 Front End

## SYNOPSIS

**pop3front-auth** *cvm* *program* \[ *args ... \]*

**pop3front-maildir** \[ *default-maildir* \]

## DESCRIPTION

The POP3 front end is composed of two pieces: an authentication front end and a transfer back-end.

Connections are timed out after *$TIMEOUT* seconds of inactivity (defaults to 1200 seconds or 20 minutes), or *$SESSION\_TIMEOUT* seconds after the connection was established (defaults to 86400 seconds or 24 hours).

**pop3front-auth** authenticates the username and password sent by the client using the named *cvm*. If successful, it sets up the environment and executes *program*. It also offers RFC 1734 complient AUTH support through \`\`cvm-sasl''.

**pop3front-maildir** serves messages via POP3 out of a maildir. If *$MAILBOX* is set, its contents are used as the path to the mailbox, otherwise the *default-mailbox* argument must be present. If *$MAX\_MESSAGES* is set, the total number of accessable messages will be limited to that number. In addition, if either of *$MAX\_CUR\_MESSAGES* or *$MAX\_NEW\_MESSAGES* are set, the total number of accessable messages in the "cur" and "new" subdirectories respectively will each be limited to that number.
