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.

Look for nocanonify in in the files SECURITY and TUNING
