Hi,

after a recent pull (I think it was on Monday, but it might actually
be completely incidental, I don't know yet) I have started to get some
problems with receiving mail from one of the mailing lists I subscribe
to.  The errors in the smtpd log look like this:

prunelle Jan 26 08:59:29 [bazar2.conectiva.com.br/200.140.247.68] bazar2.conectiva.com.br!lua-bounces -> tombob.com!rrlua sendercheck: deferred: smtp ping: smtp: dns: dns failure (/net/tcp!bazar2.conectiva.com.br)

The dns failure is coming from validatesender, which I thought was
only executed if verifysenderdomain is on in the stmpd.conf.  But
looking at the source of smtpd, it looks as if validatesender always
gets executed, regardless of smtpd.conf or the -r option to smtpd.

I don't understand the dns failure though, as it is clearly resolving
as is shown in the log entry (200.140.247.68).  What else could be the
reason for such a failure?

Thanks,
Robby
