Special Forums Cybersecurity how to hide the IP in the email header? Post 5308 by Neo on Friday 10th of August 2001 09:17:54 AM

Yes, now that the use of email has matured, a more robust and secure email protocol would be appropriate. However, it is both human nature and the nature of the IETF to 'pave over cowpaths' so there is little chance that SMTP will be redesigned (and actually used) in the next decade. The trends in IT are to modify and tweak broken legacy systems.

So, we are 'stuck with SMTP' for the forseeable future. However, mail can be sent using SMTP quite securely using PGP and other encryption methods. Originating IP addresses can be hidden; or anonymous remailers can be used (or both!!).

Net::SSLGlue::SMTP(3pm) 				User Contributed Perl Documentation				   Net::SSLGlue::SMTP(3pm)

NAME
Net::SSLGlue::SMTP - make Net::SMTP able to use SSL SYNOPSIS
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 => ... ); DESCRIPTION
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. METHODS
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. SEE ALSO
