# sendmailconfig(8)

configure sendmail for Debian systems

## NAME

sendmailconfig - configure sendmail for Debian systems

## SYNOPSIS

sendmailconfig \[--no-reload\]

## DESCRIPTION

**sendmailconfig** is used to simplify the configuration of [sendmail(8)](/sendmail/8.md) for use on Debian systems.

In the simplest case, you may run this program to (re)configure sendmail for your Debian system at any time. It will modify the file /etc/mail/sendmail.mc in order to create a working sendmail configuration which will be written to the file /etc/mail/sendmail.cf.

For advanced configurations, you can modify the sendmail.mc file before generating sendmail.cf. Future invocations of **sendmailconfig** will preserve these changes provided they are made at the end of the file.

Normally **sendmailconfig** will ask if you want to reload sendmail after making changes to its configuration. The --no-reload option will avoid this question.
