Hello,

Net::SMTP's sub auth() begins as:

  sub auth {
    my (\$self, \$username, \$password) = \@_;
  
    eval {
      require MIME::Base64;
      require Authen::SASL;
    } or \$self->set_status(500, ["Need MIME::Base64 and Authen::SASL 
+todo auth"]), return 0;
[download]

In line 117, change Authen::SASL to Authen::SASLX, a non-existant module. One would think that the error message of line 118 would be given to the user. However, the failure is silent! Why?

Code to test is attached below -- need to provide a valid $smtp_host. Output from test is attached also.

Thanks
