How to use Email::Mime with sendmail - perl

Question

I am trying to send HTML email using a script. I will have to use native unix things and Email::Mime since those are the only thing I found installed in the box i am stuck with. I am creating a Email::Mime message and sending it to sendmail.
But i keep getting Error: No recipient addresses found in header
I have seen other RUBY scripts using sendmail so that works for this box.
Can someone help me with what I might be doing wrong in the below snippet?
sub send_mail(){
use MIME::QuotedPrint;
use HTML::Entities;
use IO::All;
use Email::MIME;
# multipart message
my #parts = (
Email::MIME->create(
attributes => {
content_type => "text/html",
disposition => "attachment",
encoding => "quoted-printable",
charset => "US-ASCII",
},
body_str => "Hello there!",
),
);
my $email = Email::MIME->create(
header_str => [
To => 'abc#xxx.com',
From => 'abc#xxx.com',
Subject => "Test Email",
],
parts => [#parts],
);
# die $email->as_string;
# die YAML::XS::Dump(\%mail);
open(MAIL, "|/usr/sbin/sendmail -t");
print MAIL $email;
close (MAIL);
}
Thanks in advance.

Answer 1

print MAIL $email;
should be
print MAIL $email->as_string;

Answer 2

First of all, if your E-Mail server requires authentication (which most do of course), you need to specify a SMTP session:
$transport = EMail::Sender::Transport::SMTP::Persistent->new({
# host, port, ssl, etc
})
Furthermore, I think you don't actually need to create the content as an own MIME-content.
I did use something similar to this in my own work:
$email = Email::MIME->Create(
header_str => [ ... ],
body_str => $message,
attributes => {
charset => 'UTF-8',
encoding => 'base64',
content_type => 'text/html',
}
)
After sending your mail via sendmail($email, { transport => $transport }), you need to close the session through $transport->disconnect.
For your application you might to adapt several things like the actual sending protocol (if different from SMTP) or the attributes hash contents.
