s
sendmail(1M) sendmail(1M)
ConnectionRateThrottle=
N
Use this option to set the maximum number of connections per second to the SMTP port
to N.
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. How-
ever, 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.
DontBlameSendmail=
options
This options allows you to bypass some of
sendmail file security checks at the expense
of system security. This should be used only if you are aware of the consequences. The
options available for

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 returning
"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.
