Hi Bernhard;

Thanks for the patch. This does seem to be progress, but I don't think
it completely fixes Axel's bug. At least for me I still see

 -> .
nullmailer-smtpd: Error catching the return value from nullmailer-queue: No child processes
nullmailer-smtpd: Error catching the return value from nullmailer-queue: No child processes
<** 451 4.3.0 Error returned from nullmailer-queue

and I get a non-zero exit code. I think the problem you found was
probably a crash during the reporting of the error message.
