Rebuilding the alias database

The DB or DBM version of the database may be rebuilt explicitly by executing the command

newaliases
This is equivalent to giving sendmail the -bi flag:
/usr/sbin/sendmail -bi

If the RebuildAliases (old D) option is specified in the configuration, sendmail will rebuild the alias database automatically if possible when it is out of date. Auto-rebuild can be dangerous on heavily loaded machines with large alias files; if it might take more than the rebuild timeout (option AliasWait, old a, which is normally five minutes) to rebuild the database, there is a chance that several processes will start the rebuild process simultaneously.

If you have multiple aliases databases specified, the -bi flag rebuilds all the database types it understands (for example, it can rebuild NDBM databases but not NIS databases).
