>Description:
since version 8.12.1 (8.12.0 ?) sendmail complains if a program piping
data to it doesn't have stdin, stdout and stderr opened; smtpfwdd
doesn't open stdout and stderr when forwarding a mail to sendmail,
therefore an anoying system messages is generated for each incoming mail:
Dec 30 00:05:44 alchemy sendmail[96078]: SYSERR(uucp): File descriptors missing on startup: stdout, stderr: Bad file descriptor
>How-To-Repeat:
use current ports/mail/sendmail (version 8.12.1) together with smtpd
>Fix:
just open /dev/null as stdout and stderr...
