    I have posted this before, thinking I have some sort of dns problem

    my public mail server logs this sometimes

    sendmail[246758]: 38G6ZP06246744: SYSERR(root): timeout writing message
    to mail.example.com.
    sendmail[246758]: 38G6ZP06246744: to=<xxx@example.com>, delay=00:00:02, xdelay=00:00:01, mailer=esmtp, pri=304697, relay=mail.example.com.
    [x.x.x.x], dsn=4.0.0, stat=Deferred: Name server: mail.example.com.:
    host name lookup failure


    and the local mail server logs these.


    sendmail[29938]: 38G6ZTQv029938: collect: premature EOM: unexpected close sendmail[29938]: 38G6ZTQv029938: collect: unexpected close on connection
    from xxxxxxx, sender=<xxxxxxxxx@xxxxxxxxxxx>

    I managed to save this message and don't really know what to look for. Increasing logging also does not give anything useful.

    Run

    dig mx mail.example.com.

    And post the output here.

    If that doesn't give you SOA or the MX records, something is wrong. Try
    dig ns mail.example.com. and then

    Directly ask the authoritative with dig mx mail.example.org @nsx...
    from the output of the NS records.

    Dns is fine. I forgot to mention, I can send an email to this email
    address without any issues. Currently the messages stuck in the queue
    are only from icloud.com and me.com.

    I messed with the mailer table a bit, and I think I bounced them.
    However the mailq command indeed showed a

    (host map: lookup (someexternalhost.com): deferred)

    someexternalhost.com was indeed not resolving and was mentioned in the
    cc/to headers.

    So we have a message that has:

    for <aaaa@formyhost.com>;

    From:xxxx@icloud.com

    To: aaaa@formyhost.com, bbbb@formyhost.com, cccc@someexternalhost.com

    But what I do not get is why the 'cccc@someexternalhost.com' gives me
    local delivery issues.

    Please run mailq and post the output here without changing the domains.
    Also run
    sudo sendmail -q -v and post the output here.
