Hi peter,

yeah my server does retries but always ends up on the mailserver with the lower priority :(

I have a mail to deliver to a domain that has two mx record but the

I would question their competence right there. If it's an MX, it needs
to actually handle mail. (Ok, there is the slightly perverse case
where the only thing actually listening on port 25 is spamd(8), but stil
l)

So far so good the priority on the 2nd mx is also lower so my
sendmail daemon should figure to send to the server with the
highest priority but it does not.

So here is what I have done to get my server to try to deliver the
mail to the right server:

- restarted sendmail - restarted named

Is there something I can do still to get my sendmail to deliver to
the mailsserver with the higher priority?

As long as your side keeps retrying, it will eventually manage to
deliver to the one that actually accepts mail. But please tell the
other side to just fix their setup.

I talked to the guy on the other "Mailserver" side and he says we
are the only one who have a problem since they deployed that setup
in 2014.

The only one seeing the problem? No. The only one looking into the
problem and telling them about it? Quite possible. As in, most people
wouldn't know what to look for, and in most cases mail would
eventually be delivered anyway, but delivery would not happen immediatel
y.

The only advice I can offer is to check that your side has a
reasonable retry period (IIRC default setups for all the MTAs on
OpenBSD come with reasonable settings, but do check), and tell the
other side that for their own sake they need to fix their setup.
