Net::SMTP uses Authen::SASL internally to do the authentication. You should check to make sure that this is installed on both machines. Authen::SASL comes in several flavours, including Authen::SASL::Perl (pure perl) and Authen::SASL::Cyrus (using XS to link to the cyrus libraries). Check that you have the same one installed on both systems.

You're not doing any error checking in the above code either. You should make sure that each of the auth(), mail(), to(), and data() functions return a true value, and if they do not, use the $smtp->message() method to get the error message back.

You can use Ethereal to look at what is actually being sent to your mail server too - this is sometimes useful
