sendmail failure

[ianjhart]

That post about AAAA lookups reminds me; the one 5.x box I'm running at work, 
refuses to deliver it's log files to our mail hub. I know that there are 
about a million different ways for me to have stuffed this up myself, so 
please be gentle.

That other post reminds me about this because we have broken (i.e. MS) DNS 
servers. The 4.10 boxes we have all deliver okay though. I'm wondering if 
WorkAroundBrokenAAAA is okay in 5-STABLE.

Anyway I've done side by side comparisons of two servers. They look similar up 
to the point where the 4.x server opens a network connection and gets the 220 
reply. The 5 box apparently does nothing. Using tcpdump, It looks like the A 
request is never sent, so there's no connection opened.

If I run
#echo test | sendmail -Am -v -d16.10 root

on the 4.10 box the output includes

makeconnection: WorkAroundBrokenAAAA: Trying AF_INET lookup (AF_INET6 failed)
makeconnection (mail.lan.cardinalnewman.coventry.sch.uk. [10.248.192.10].25 
(2))
makeconnection: fd=7

My workstation at home (with 4.10 DNS) shows

makeconnection (alpha.private.lan. [192.168.0.2].25 (2))
makeconnection: fd=7

but the 5.3 box at work shows no makeconnection output at all.

Box was built Aug 2nd and updated from source.

stock sendmail AFAIR; rebuilding everything just in case.
