scrlttr2 addrfield=false

I frequently have to write letters of recommendation. These are not addressed to a particular recipient. They are typically held by one person and sent to a variety of places, so there is no point in specifying a recipients' address.

I also use preprinted letterhead from my college for the first page. The preprinted logo takes 2 inches on the top and the preprinted address takes 1 inch on the bottom.

I have a problem with using scrlttr2 for these letters that I cannot solve. The same amount of vertical space is always present. The vertical distance between the top of the page and the date is the same whether I specify a recipients' address or not.

After reading the manual and looking at the .cls file, I thought that addrfield=false would remove this space. But I seem to have misunderstood.

Is there a way of starting the letter closer to the top of the page?

Here is a minimal example. With longer letters, I get a paragraph or two on the first page and the rest on the second page.

\documentclass[fontsize=11pt, paper=letter]{scrlttr2}
\usepackage[american,british]{babel}
\datebritish
 
\KOMAoptions{%
	addrfield=false,% Switching this on or off doesn't make any difference in the vertical space between the top of the page and the date, subject, salutation, etc..
	backaddress=false,
	BCOR=0mm,
	enlargefirstpage=true,
	foldmarks=false,
	fromalign=false,
	fromrule=false,
}
 
\typearea[current]{calc}
\firsthead{}
 
\renewcommand{\raggedsignature}{\raggedright} % make the signature ragged right
 
\setkomavar{fromname}{Michael Green}
 
\setkomavar{signature}{Michael Green \\ My Title} % printed after the \closing
 
\setkomavar{subject}{Letter of Recommendation for Mr. Lorem Ipsum} % subject of the letter
 
\begin{document}
 
\begin{letter}{Mr. Recipient \\ 456 Hard Ave. \\ Springfield, MA, 67890}
 
\opening{To whom it may concern:} % eg. Hello, dear, etc.; make empty for rec letter
 
Lorem ipsum dolor sit amet, and so on.
 
\closing{Sincerely yours,} %eg. Regards
 
\end{letter}
\end{document}

Thank you very much.
