This is harder than I initially hoped.
I've decided to do my rewriting at the very beginning of rwrecip
in courier/module.esmtp/esmtp.c, right before the first
rfc822check hits.

Now I'm stuck though, partly because my C isn't that great anymore,
partly because I don't know how I'm supposed to do things like
alloc memory in courier.

Currently my additional code looks like this

      for (p=0, s=info->ptr; s; s=s->next)
          if (s->token == '@')        p=s;
      if (p==0) {     // no @ in address, we need to rewrite
          // let's find the last token
          for (s=info->ptr; s->next; s=s->next);

and now I need to alloc a new rfc822token, alloc a string with
my defaultdomain, and fill the rfc822token with the right info.
I guess. :)

Any helpful hints? ("ask on courier-devel" is a valid hint :)

tia,
