 Your code works for me. From my point of view, the pros are that per
 default `org-koma-letter-{author,sender}' pick up the values of
 `user-full-name' and `user-mail-address' whenever they are changed.
 That's very nice! The cons are that IHMO it's quite complicated for
 setting something as simple as author and email and you mentioned a
 possible crash which I did not test further. Could this be tested using
 `functionp'? Still, I think we should stick with it for now.

 functionp seems better, yes.  I didn't know about it (doh!).  Thanks!

 While it is complicated I think it's OK given our desire to disable
 author and still have a similar default to ox-latex.el.  Also, it
 allows for arbitrary functions which could potentially determine the
 name based on the context of the letter (I don't know since it's
 already initialized in the options-alist).

 I'll let you and Alan decide.

I like this approach.

 As a side note, I had quite a few problems working with your patches.
 None of them applied against master, or against my latest patch as you
 claimed. 

 Right.  I was working off of branch and I guess one reasons is that it
 was against the history of my previoues patches—of which not all was
 applied to the master, it seems (?).  I've now tried to rework the
 entire thing against the current master and produces simplified
 patches.  I tested them with git am and they work on my system.

 There are still things I don't understand such as why git wants to
 re-add the authors in patch 4 but I've spend way to much time on
 rebasing and understanding git already and my head hurts.  It seems to
 ignore it when using git am.

 Before applying the patches my git log says

Hi Xavier,

 1. summarizes all changes in author.  It uses my solution as mentioned 
 above.
 2. full support for after closing keywords.  See commit message
 3. signature to nil
 4. change handling of subject and allow for setting subject in
 OPTION-line.

 I'm going to apply the patches. Thanks to both of you for the nice work!

 I just update Org/git and install ox-koma-letter lisp file. I have a
 strange behavior with EMAIL keyword since there will be always a
 =\setkomavar{fromemail}= command in my LaTeX produced file even if
 there is no #+EMAIL: keyword on top of my org file. This is slightly
 different from what I get when I write or not #+AUTHOR: keyword : the
 =\setkomavar{fromname}= naturally disappears if AUTHOR is not written.

Thanks for the quick report, and sorry about the inconvenience.

I'm kind of busy this week due to obligations which I must attend to.

Could you perhaps set the offending variable to nil for now?  Either
org-koma-letter-email or the org-koma-letter-use-email or use
#+OPTIONS: email:nil.

I couldn't see what would be causing the offending behavior straight
away.  Could you give me an example-file where the behavior fails?
Then I'd also be able to test that future changes don't break expected
behavior.

Also, if time permits please do look over the (hopefully) elaborate
changelogs and test that everything works as you expect it to.

 I do not want to write every time my email in org file header since it
 is already set in a lco file. But given this problem, the email is
 always overloaded when exporting to latex/pdf.

If you always have an email in you lco file you should disable email
publishing.

Cheers,
Rasmus

 Subject: [PATCH 1/4] ox-koma-letter.el: Reintroduce variables removed in
  commit 832c6fd with proper defaults.
 
   * ox-koma-letter.el (org-koma-letter-author): Dedicated
   variable to set the KOMA variable fromname; initialized to
   `user-full-name' using `after-init-hook' if not set
   explicitly.
   (org-koma-letter-email): Dedicated variable to set the KOMA
   variable fromemail; initialized to `user-mail-address' using
   `after-init-hook' if not set explicitly.
   (koma-letter): Use dedicated variables for AUTHOR and EMAIL.
   (org-koma-letter-template): Variable name change.
 
 Setting the variables `org-koma-letter-author' and `org-koma-letter-email' to 
 the values of `user-full-name' and `user-mail-address' respectively, allows 
 the user to skip =#+AUTHOR:= and =#+EMAIL:= lines when configuring a letter. 
 However, if the user wishes to set this information in LCO files, these 
 variables need to be set to nil.

 This patch makes the subject option easier although still relying on

 default is t corresponding to do nothing but print komavar subject.

 A potential problem is that subject default to the file name and can

I'm also not a big fan of the title defaulting to the filename. But I

Viktor,

   1. Viktor's latest patch.
   2. The patch describe above that gets user name and email and works
  on my system. . .

 Your code works for me. From my point of view, the pros are that per
 default `org-koma-letter-{author,sender}' pick up the values of
 `user-full-name' and `user-mail-address' whenever they are changed.
 That's very nice! The cons are that IHMO it's quite complicated for
 setting something as simple as author and email and you mentioned a
 possible crash which I did not test further. Could this be tested using
 `functionp'? Still, I think we should stick with it for now.

functionp seems better, yes.  I didn't know about it (doh!).  Thanks!

While it is complicated I think it's OK given our desire to disable
author and still have a similar default to ox-latex.el.  Also, it
allows for arbitrary functions which could potentially determine the
name based on the context of the letter (I don't know since it's
already initialized in the options-alist).

I'll let you and Alan decide.

 As a side note, I had quite a few problems working with your patches.
 None of them applied against master, or against my latest patch as you
 claimed. 

Right.  I was working off of branch and I guess one reasons is that it
was against the history of my previoues patches—of which not all was
applied to the master, it seems (?).  I've now tried to rework the
entire thing against the current master and produces simplified
patches.  I tested them with git am and they work on my system.

There are still things I don't understand such as why git wants to
re-add the authors in patch 4 but I've spend way to much time on
rebasing and understanding git already and my head hurts.  It seems to
ignore it when using git am.

Before applying the patches my git log says

Yeah, could be better.  It's way too hectic with all the patches and
keeping track of moving repos.  If you think it can ease the burden of
collaborating I'm all for it.

I tried to make a git repo retaining the history of ox-koma-letter.el,
but I ended up with a repo of 42mb even after applying all the
garbage collection tips the interweb had to offer. . .

I'm indifferent between bitbucket and github btw, but I'd prefer it
someone with more git skills would set it up.

Setting the variables `org-koma-letter-author' and
`org-koma-letter-email' to the values of `user-full-name' and
`user-mail-address' respectively, allows the user to skip =#+AUTHOR:=
and =#+EMAIL:= lines when configuring a letter. However, if the user
wishes to set this information in LCO files, these variables need to
be set to nil.

With the old after-init-hook method my user name was always set to .
Now org-koma-letter will (i) allow for default nil values (good if you
use LCO files); (ii) default to =`user-full-name'= and
=`user-mail-address'= like =ox-latex.el=.  These values are obtained
on-the-fly.

The two variables in question can also be strings or functions
returning strings.
