# qmail-control(5)

qmail configuration files

## NAME

qmail-control - qmail configuration files

## INTRODUCTION

You can change the behavior of the **qmail** system by modifying **qmail**'s *control files* in **/var/lib/qmail/control**.

**qmail** can survive with just one control file, *me*, containing the fully-qualified name of the current host. This file is used as the default for other hostname-related control files.

Comments are allowed in *badmailfrom*, *locals*, *percenthack*, *qmqpservers*, *rcpthosts*, *smtproutes*, and *virtualdomains*. Trailing spaces and tabs are allowed in any control file.

The following table lists all control files other than *me*. See the corresponding man pages for further details.
