    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.

    #uname -a
    FreeBSD client.lan.cardinalnewman.coventry.sch.uk 5.3-STABLE FreeBSD
    5.3-STABLE #8: Thu Dec 23 00:45:38 GMT 2004
    ict@client.lan.cardinalnewman.coventry.sch.uk:/usr/obj/usr/src/sys/GENERIC
    i386

    Box was built Aug 2nd and updated from source.

    stock sendmail AFAIR; rebuilding everything just in case.
