Hi,
Please tell me what is sendmail masquarade and what is the use of it?

FEMAIL(8) BSD System Manager's Manual FEMAIL(8)
NAME
femail -- accept mail on behalf of a real MTA
SYNOPSIS
femail [-46tv] [-f from] [-F name] [address ...]
DESCRIPTION
femail is intended to be used on servers that do not run a real MTA or inside chroot(8) environments. It features a sendmail(8)-compatible
command line interface and forwards mail via SMTP to the host given in the config file, an environment variable or localhost.
The options are as follows:
-4 Only use IPv4.
-6 Only use IPv6.
-F name Set the sender's name to name.
-f from Set the sender address to from. Normally, femail tries to parse the sender from the message, and uses login@hostname if that is
not present.
-t Read recipients from the message given on stdin, in addition to the recipients given on the command line.
-v Enable verbose operation.
CONFIG FILE
The config file, /etc/femail.conf, consists of simple name=value pairs. The supported settings are as follows:
smtphost Specify the server femail should send the messages to.
smtpport Specify the port femail uses on smtphost to send the messages. Default is 25.
myname The hostname femail uses. Defaults to the machine's hostname.
ENVIRONMENT
SMTPHOST Forward mail to the given host instead of the local host. Only consulted when not set in the config file.
SMTPPORT Connect to the given port instead of 25. Only consulted when not set in the config file.
SEE ALSO
mail(1), sendmail(8)
