Constants

CHUNK_DEFAULT

public mixed CHUNK_DEFAULT = 1048576

Properties

$data_8bit read-only

public bool $data_8bit

Does server support sending 8-bit MIME data?

$data_binary read-only

public bool $data_binary

Does server support sending binary MIME data? (@since 1.7.0)

$data_intl read-only

public bool $data_intl

Does server support sending internationalized (UTF-8) header data? (@since 1.6.0)

$size read-only

public int $size

The maximum message size supported (in bytes) or null if this cannot be determined.

$_connection

Connection to the SMTP server.

protected Horde_Smtp_Connection $_connection

$_debug

The debug object.

protected Horde_Smtp_Debug $_debug

$_ehlo

LMTP only supports LHLO hello command (RFC 2033 [4.1]), not EHLO.

protected string $_ehlo = 'LHLO'

HELO isn't supported, but HELO code in _hello() should not be reached since failure of LHLO command will result in 500 error code (instead of 502 necessary to fallback to HELO).

$_extensions

The list of ESMTP extensions.

protected array<string|int, mixed> $_extensions = \null

If this value is null, we have not connected to server yet.

$_params

Hash containing connection parameters.

protected array<string|int, mixed> $_params = array()

$_requiredExts

These extensions are required for LMTP (RFC 2033 [5]).

protected array<string|int, mixed> $_requiredExts = array('ENHANCEDSTATUSCODES', 'PIPELINING')
