I checked, the keys seem to validate (although I don't really understand
how) I used the autoresponder checking e-mail addresses on some sites. I
don't think I have feature masquerade activated in sendmail, but I'll check.
In fact it is a bit of a problem to tell daemons on ux to not use
localhost.localdomain. I solved that for squirrelmail by editing the
userprofile to show the correct reply-to address.
