| Variable | Purpose
|
|---|
| confSMTP_LOGIN_MSG | This defines the one-line
message which is displayed when a remote MTA connects to
sendmail's SMTP port. Variable expansion is done for many
variables, including:
- $j
- local hostname
- $v
- version of the sendmail binary
- $Z
- version of the sendmail.cf file
- $b
- current time
This can be changed for fun to something like $j sendmail
$v/$Z ready to serve your every whim at $b.
|
| confMAX_MESSAGE_SIZE | This is the maximum
message size allowed for local delivery. I recommend setting this to
5242880 (5MB) to avoid mail bombs.
|
| confPRIVACY_FLAGS | This allows you to set some
restrictions on what other users are allowed to find out about
sendmail's operation. Common values are:
- authwarnings
- Issue warnings about authenticity of
header information.
- restrictqrun
- Only allow root to run the
mail queue manually.
- restrictmailq
- Only allow root to see the
contents of the mail queue.
- noexpn
- Do not allow the SMTP EXPN
command, which allows remote users to see the result of an alias
expansion on the local machine.
- novrfy
- Do not allow the SMTP VRFY
command, which allows remote users to verify the existance of a user
account on your machine.
Multiple privacy flags can be specified, seperated by commas.
