newaliases : initialize the alias database
[SYNOPSIS] newaliases OPTION
OPTION
-bd Go into daemon mode.
This mode of operation is implemented by executing the "postfix start" command.
-bl Go into daemon mode.
To accept only local connections as with Sendmail's -bl option, specify "inet_interfaces = loopback" in the Postfix main.cf configuration file.
-bm Read mail from standard input and arrange for delivery. This is the default mode of operation.
-bp List the mail queue. See the mailq command above.
-bv Do not collect or deliver a message. Instead, send an email report after verifying each recipient address.
This is useful for testing address rewriting and routing configurations.
