Hi, % sendmail -t -i -fReturn-Path: /dev/null@alea.gnuu.de sendmail: recipients with -t option not supported % echo $? 0 The call above is wrong, I know, but ssmtp doesn't tell so via exit code which makes the caller, e.g. PHP, think everything was fine. This is not good. Ssmtp should return with an exit code different from zero. Bye, Jörg.
