Rewriting the From Line on Outgoing Mail
HP provides a method that allows the From line on a mail message to be rewritten.
This can be useful when a user’s login name does not clearly identify the user to
intended mail recipients. For example, mail sent by bkelley (mailname) can be
changed to read as Bob_Kelley (maildrop).
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
5. Uncomment the first rule in ruleset 94.
Forwarding Your Own Mail with a .forward File
You can redirect your own mail by creating a .forward file in your home directory.
If a .forward file exists in your home directory and is owned by you, Sendmail
redirects mail addressed to you to the addresses that the .forward file contains.
