Hi list,
I'm glad to see that my mail from yesterday did finally leave the queue
of my netqmail install.
I'm recently having trouble to send mail to lists.gentoo.org via my
netqmail. It says that it is _temporarily_ unable to do a CNAME lookup.
But mails stay in queue until they eventually bounce. I have now configured
a static smtp route to pigeon.gentoo.org and mails seem to go through.
I'm currently using google's DNS in /etc/resolv.conf (But the results from
the DNS server of my ISP are the same):
I think that the real problem is, that $(dig @8.8.8.8 lists.gentoo.org any) [1]
doesn't give me a MX-Record at all. Also, directly asking for a MX-Record
doesn't seem to report one[2].
I'm not too deep into DNS, so I'm asking for any clues on how to really
solve this issue?
Sascha

In your DNS queries you did "list.gentoo.org", the actual FQDN is
"lists.gentoo.org"

Oh, I see, you're right of course that was a typo in my testing - and indeed
with the typo fixed I get correct looking MX-Records via dig from both google
and my ISP. However, that makes me just a bit more curious on what's going
wrong here.
I'll remove my smtproute before sending this mail. Just in case it was really
some "temporary" thing for approximately the last two weeks.

Doesn't look so... :-[
I've meanwhile found out that it might be related to a DNS lookup bug inside qmail and
found an old patch that should addresses this issue. The patch is short and looking
innocent to me, so I've now setup a local overlay and am trying to send this out
without the smtproute, once again.

Okay, this last mail went through smoothly and without any trouble in log
files.
Since I got private mails from others having the same problem, here's exactly
what I did to solve this:
- Create a local overlay
- copy the mail-mta/netmail directory from portage tree
- wget http://www.ckdhr.com/ckd/qmail-103.patch
to the files directory.
- copy netmail-1.06.ebuild to netmail-1.06-r1.ebuild
- insert "epatch "${FILESDIR}"/qmail-103.patch" before the first epatch in
src_unpack()
- rebuild manifest, add the overlay and rebuild netmail
- restart svscan.
This patch from Christopher Davis is actually dated back to 1998; I'm not sure
about copyright issues on the patch, but it seems trivially simple.
Though, I'm wondering why such a simple fix isn't already part of the netmail
ebuild.

Thanks for posting the fix! :-)
Now, how about filling a bug... ;-)
