Binary package hint: ssmtp
Hi,
I recently found that if I set rewriteDomain to <email address hidden> and try to send email with ssmtp, it dies rather horribly. The docs on ssmtp are pretty sparse so I may be using the directive wrong but either way it shouldn't crash like this. See below...

the syslog does indeed show:
Jan 4 10:06:32 ringmaster2 sSMTP[15849]: Set RewriteDomain=
Jan 4 10:06:32 ringmaster2 sSMTP[15849]: Set RewriteDomain=
and when I correct it the crash goes away, but it really shouldn't crash having detected a small config error.
