Net::SSLGlue::SMTP - make Net::SMTP able to use SSL
use Net::SSLGlue::SMTP;
my $smtp_ssl = Net::SMTP->new( $host,
SSL => 1,
SSL_ca_path => ...
);
my $smtp_plain = Net::SMTP->new( $host );
$smtp_plain->starttls( SSL_ca_path => ... );
Net::SSLGlue::SMTP extends Net::SMTP so one can either start directly with SSL
or switch later to SSL using the STARTTLS command.
By default it will take care to verify the certificate according
to the rules for SMTP implemented in IO::Socket::SSL.
- new
- The method "new" of Net::SMTP is now
able to start directly with SSL when the argument
"<SSL =" 1>> is given. In this
case it will not create an IO::Socket::INET object but an IO::Socket::SSL
object. One can give the usual "SSL_*"
parameter of IO::Socket::SSL to
"Net::SMTP::new".
- starttls
- If the connection is not yet SSLified it will issue the STARTTLS command
and change the object, so that SSL will now be used. The usual
"SSL_*" parameter of IO::Socket::SSL
will be given.
- peer_certificate ...
- Once the SSL connection is established the object is derived from
IO::Socket::SSL so that you can use this method to get information about
the certificate. See the IO::Socket::SSL documentation.
All of these methods can take the
"SSL_*" parameter from IO::Socket::SSL to
change the behavior of the SSL connection. The following parameters are
especially useful:
- SSL_ca_path, SSL_ca_file
- Specifies the path or a file where the CAs used for checking the
certificates are located. This is typically "etc/ssl/certs" on
UNIX systems.
- SSL_verify_mode
- If set to 0, verification of the certificate will be disabled. By default
it is set to 1 which means that the peer certificate is checked.
- SSL_verifycn_name
- Usually the name given as the hostname in the constructor is used to
verify the identity of the certificate. If you want to check the
certificate against another name you can specify it with this
parameter.
