There is a bug in that grep. I assumed error messages would start on
a new line, but that is not true. Here is the fix:

grep -v '^[[:space:]]*password:[[:space:]]*$'

And when I fixed that, then I discovered a warning message from the
server, that I didn't want mails for. So here is the next version:

grep -v 'hasnoatt\|^[[:space:]]*password:[[:space:]]*$'

I may be the only living person who cares about this, but for anyone
who finds this thread in an archaeological dig a thousand years from
now, you may have to tinker with the grep to get it working the way
you want. :-)
