mail aliases

[S Gruver]

1. What does this error message mean:
'cannot open hash database /etc/mail/aliases.db invalid argument' ?

2. How/where does it get fixed?

Thanks

It is possible that the aliases.db file is corrupted or not present on the
system anymore. To rebuild it, use the newaliases command (or sendmail -bi).
This should force a rebuild of the aliases.db file and clear the error you're
seeing.

The file /etc/mail/aliases is the list of aliases. You may need to check this
file, too - if it isn't present or is damaged, the newaliases will most likely
fail.
