sendmail 8.12.7 squawking after MS 4.11-1 upgrade

[Jeremy Evans]

Unfortunately, after applying the patch, I'm still getting the error:

sendmail[30488]: File descriptors missing on startup: stderr; Bad file
descriptor

This is on an OpenBSD 3.2 box.  I rebooted the machine beforehand, and still
got the error when I sent a message.  Then I killed MailScanner and sent a
message, without getting an error (so it goes into mqueue.in without
problems).  When I restarted MailScanner, I got the error shortly thereafter
(probably when it transfers the mail back to sendmail to send out).  I
haven't had a problem with mail being modified or deleted (except when it is
supposed to, i.e. bad attachment filename), so the message is more of an
annoyance than anything else.  Still, it would be nice to get rid of it.

Oops, you're right of course.
Must remember not to code with one hand while drinking wine with the other
:-)
