. executable FILENAME

. helo_domain HOST

=over 4

The fully qualified name of the sender's host (your system) which
is used for the greeting message to the receiver.  If not specified,
Net::Config or else Net::Domain are questioned to find it.
When even these do not supply a valid name, the name of the domain in the
C<From> line of the message is assumed.

=back

. hostname HOSTNAME|ARRAY-OF-HOSTNAMES

. interval SECONDS

. log LEVEL

. password STRING

=over 4

The password to be used with the new(username) to log in to the remote
server.

=back

. port INTEGER

. proxy PATH

. retry NUMBER|undef

. smtp_debug BOOLEAN

=over 4

Simulate transmission: the SMTP protocol output will be sent to your
screen.

=back

. timeout SECONDS

=over 4

The number of seconds to wait for a valid response from the server before
failing.

=back

. trace LEVEL

. username STRING

=over 4

Use SASL authentication to contact the remote SMTP server (RFC2554).
This username in combination with new(password) is passed as arguments
to Net::SMTP method auth.  Other forms of authentication are not
supported by Net::SMTP.  The C<username> can also be specified as an
Authen::SASL object.

=head2 Sending mail


$obj-E<gt>B<destinations>(MESSAGE, [ADDRESS|ARRAY-OF-ADDRESSES])

=over 4

See L<Mail::Transport::Send/"Sending mail">

=back

$obj-E<gt>B<putContent>(MESSAGE, FILEHANDLE, OPTIONS)

=over 4

$obj-E<gt>B<send>(MESSAGE, OPTIONS)

=over 4

See L<Mail::Transport::Send/"Sending mail">

=back

$obj-E<gt>B<trySend>(MESSAGE, OPTIONS)

=over 4

Try to send the MESSAGE once.   This may fail, in which case this
method will return C<false>.  In list context, the reason for failure
can be caught: in list context C<trySend> will return a list of
five values:

 (success, error code, error text, error location, quit success)

Success and quit success are booleans.  The error code and -text are
protocol specific codes and texts.  The location tells where the
problem occurred.

 Option  Defined in       Default
 from                     []     
 to                       []

taken from the C<From> field in the header.

=back

. to ADDRESS|[ADDRESSES]

=over 4

Alternative destinations.  If not specified, the C<To>, C<Cc> and C<Bcc>
fields of the header are used.  An address is a string or a Mail::Address
object.

=head2 Server connection


$obj-E<gt>B<contactAnyServer>
