Sendmail, 3rd Edition

Name

ph

Synopsis

Prior to V8.10 sendmail, redirecting email with a ph server required running the phquery program. Beginning with V8.10 sendmail, a database-map type called ph has been added that allows sendmail to perform direct ph queries. You declare it like this:

Kname ph  switches

The complete list of switches for this database-map type is shown in Table 23-22.
