''-o'' '''

-o
Append to, don't overwrite the file makemap command-line switch

Ordinarily, makemap overwrites any existing map with completely new information. The -o switch causes sendmail to append to a map. The appended information must be all new information (no duplicate keys), unless the -r or the -d switch is also used.
