# cvm-checkpassword(8)

checkpassword interface for CVM modules

## NAME

cvm-checkpassword - checkpassword interface for CVM modules

## SYNOPSIS

**cvm-checkpassword** *CVM* *Command* \[ *arguments ...* \]

## DESCRIPTION

 http://cr.yp.to/checkpwd/interface.html\
  http://untroubled.org/cvm/cvm.html

See the above links for details on both the CVM and checkpassword interfaces. To use this interface with [**qmail-pop3d**(8)](/qmail-pop3d/8.md), use the following command line:

 /var/qmail/bin/qmail-popup \\\
  cvm-checkpassword cvm-unix \\\
  /var/qmail/bin/qmail-pop3d ./Maildir/

**Note:** The default mode of operations for this module is to attempt to split a domain name from the account name. If this is not desirable, set $CVM\_ACCOUNT\_SPLIT\_CHARS to an empty string.
