Early retry timeout

Hello,

I just received the following bounce from my exim server:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

fmjvisas [at] state
SMTP error from remote mail server after RCPT TO:<fmjvisas [at] state>:
host haig-ee.state.gov [169.253.194.10]: 451 4.3.2 Please try again later:
retry timeout exceeded

However, this mail was only sent a few minutes ago:

I'm using the default retry rule:

Retry rule: * * F,2h,15m; G,16h,1h,1.5; F,4d,6h;

and the retry db says:

Maybe you have set in this transport hosts_max_try = 1 ?

Nope, this option doesn't appear anywhere in my configuration.

Sounds very similar to a long standing issue which was thought to be
fixed but which still seems to turn up in very specific circumstances.
I'm sure people would be very interested in what those circumstances are
so the issue could be examined more since it is not very easily reproduced.

Yes, that looks very similar. But I'm not sure what missing information
I could add here, the first report seems to contain pretty much
everything that I would say is relevant.

Is there something in particular you are looking for that I could
provide?

Best,

Is there any other domain in your hints db that ends up going to the
same IP address and that has already timed out?

No, I don't think so:
