title: sending email using perl mail/sender with html body part
body: <p>I am new to Perl and I am trying to send an email using the <a href="https://metacpan.org/module/Mail%3a%3aSender" rel="nofollow">Mail::Sender</a> module with HTML in the body part. I am using <code>debug =&gt; 'x.log'</code> to analyze the mail sending process. </p>
  
  <p>It looks like Perl is weirdly putting 3D after each '=' sign and 20 for each space in my HTML code (looks like URL codes for  HTML). And after this no email is received at by client. What could be a problem here? (e.g. <code>border="5"</code> becomes <code>border=3D"5"</code>)</p>
  
  <p>I am using <code>$sender-&gt;SendEnc($BODY);</code> to send message and <code>$sender-&gt;Open({to =&gt; "$userAtFaultEmail", subject =&gt; "$email_subject", ctype =&gt; "text/html", encoding =&gt; "quoted-printable"'});</code> to open mail connection.</p>
