Hello tel2,

...
$msg->send or die "Error sending email!";
...

See how the response doesn't include "Error sending email!".

That’s because the code dies before $msg->send returns. Specifically, it dies on lines 2895-7 of MIME/Lite.pm:

    $smtp->mail( $args{From}, %opts ? \%opts : () )
      or die "SMTP mail() command failed: $!\n"
             . $smtp->message . "\n";

Sorry, I don’t know the cause (or the fix). But before you persevere with this module, did you notice the disclaimer in the documentation?

WAIT!

MIME::Lite is not recommended by its current maintainer. There are a number of alternatives, like Email::MIME or MIME::Entity and Email::Sender, which you should probably use instead. MIME::Lite continues to accrue weird bug reports, and it is not receiving a large amount of refactoring due to the availability of better alternatives. Please consider using something else.

If I were you, I’d try with one (or more) of the alternative modules before putting more time into MIME::Lite.

Hope that helps,
