49 * PEAR's Mail:: interface. Defines the interface for implementing
50 * mailers under the PEAR hierarchy, and provides supporting functions
51 * useful in multiple mailer backends.
54 * @version $Revision: 294747 $
60 * Line terminator used for separating header lines.
66 * Provides an interface for generating Mail:: objects of various
69 * @param string $driver The kind of Mail:: object to instantiate.
70 * @param array $params The parameters to pass to the Mail:: object.
71 * @return object Mail a instance of the driver class or if fails a PEAR Error

91 * @param mixed $recipients Either a comma-seperated list of recipients
92 * (RFC822 compliant), or an array of recipients,
93 * each RFC822 valid. This may contain recipients not

98 * associative array, where the array key is the
99 * header name (ie, 'Subject'), and the array value
100 * is the header value (ie, 'test'). The header
