AutoRebuildAliases
Use this option to rebuild the alias database when needed. Setting this option may
cause excessive overhead and is not recommended.
DontProbeInterfaces
Use this option to turn off the inclusion of all the interface names in
$=w on startup.
In particular, if you have many virtual interfaces, this option speeds up the startup.
However, unless you make other arrangements, mails sent to those addresses will
bounce. This is useful for sending mail to hosts which have dynamically assigned
names.

options

sendmail file security checks at the

DontInitGroups=True |False
Set this option to true, to prevent program deliveries from picking up extra group
privileges.
MaxRecipientsPerMessage=no_of_recipients
Use this option to limit the number of recipients, no_of_recipients that will be accepted
in a single SMTP transaction. After this number is reached, sendmail starts return-
ing "452 Too many recipients" to all RCPT commands. This can be used to limit the
number of recipients per envelope (in particular, to discourage use of the server for
spamming). Note: A better approach is to restrict relaying entirely.
MaxHeadersLength=max_header_length
Use this option to specify the maximum length of the sum of all headers,
max_header_length. This can be used to prevent a Denial-of-Service(DoS) attack.
RunAsUser=user
Use this option to enable sendmail do a setuid to that user early in processing to
avoid potential security problems. However, this means that /var/spool/mqueue
