As soon as one of the headers is not a string literal, but rather a variable coming from the outside of your program, it's much harder to correctly deal with it - you have to strip newlines and maybe quotes, escape non-ASCII-characters and so on.
Which is why I recommend to look at Yes, even you can use CPAN and see if you really can't use a module. MIME::Lite appears to be a pure-Perl module, and thus you should be able to use it everywhere where you can put scripts by yourself.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
