Rewriting the From Line on Outgoing Mail is not working

Hi,

 

Rewriting the From Line on Outgoing Mail is not working.  Could you please provide us the step by step method for configuring from line on outgoing mail. i followed the below procedure but no luck any idea where i stuck?

 

To rewrite From lines on an outgoing mail message, do the following:
1. Create the file /etc/mail/userdb, which contains two entries for
each mail user. The entries must be in the following format:
bkelley:mailname Bob_Kelley
Bob_Kelley:maildrop bkelley
2. Build the /etc/mail/userdb.db file with the makemap routine:
makemap btree /etc/mail/userdb.db < /etc/mail/userdb
3. Uncomment the following line in the /etc/mail/sendmail.cf file:
UserDatabaseSpec=/etc/mail/userdb.db
4. Add the i flag to all the mailer definitions, to enable UDB sender
rewriting. For example, change the mailer definition from
Mlocal, P=/usr/bin/rmail, F=lsDFMAw5:/|@m,
S=10/30, R=20/40, T=DNS/RFC822/X-Unix,
A=rmail -d $u
to
Mlocal, P=/usr/bin/rmail, F=lsDFMAw5:/|@mi,
S=10/30, R=20/40, T=DNS/RFC822/X-Unix,
A=rmail -d $u
