THAT'S the problem!! My mailer writes addresses I enter as
"someone@???" (without the double quotes) like follows:
"someone@???" <someone@???>

I'm well aware of these problems, but they're only of academic nature. I need
only handle these simplest cases like the above.
Thanks to your helpful hint I was able to get this running. My rewrite rule
now looks like this:
rabe@??? \
"${if and {
{def:h_To:}
{match
{$h_To:}
{\\N^(\"someone@???\" )?<?someone@???>?$\\N}
}
} {rabe-lkt} fail
}" fFrQ
I've broken the line to make it more readable, I hope it's still obvious how
the expression looks like.
The pattern recognizes addresses like the following:
"someone@???" <someone@???>
<someone@???>
someone@???
Is this, in your eyes, the optimal way of writing this, or can you give me
additional hints about how to further improve it?
Thanks,
Ralf
