Expand an alias using the command line

sendmail -bv

so assuming an /etc/mail/aliases file that looks like this:

root: ricardo
postmaster: root


An example…

# sendmail -bv postmaster
ricardo… deliverable: mailer local, user ricardo

The command will expand postmaster to root to ricardo in this case sendmail does not tell you about any aliases in the middle (e.g. root in this example)
