[BlueOnyx:24427] Re: strange issue vsite and hostname

[Tomohiro Hosaka]

Hello.

I also experienced this problem the other day.
The environment is 5209R.

In my case, the result was a mismatch between the host name in the
Let's Encrypt certificate and the reverted host name by reboot,
causing the sendmail command to fail to send mail.

# grep 'Data format error' /var/log/maillog
Oct xx xx:xx:xx hostxx sendmail[18653]: 09RFKSvw0186xx:
to=email at address.xx, ctladdr=xxxx (1001/100), delay=00:00:00,
xdelay=00:00:00, mailer=relay, pri=30210, relay=[127.0.0.1]
[127.0.0.1], dsn=5.6.0, stat=Data format error
...

When I checked the uptime, I found that there was a Data format error
between the reboot and the time I noticed it.

Thanks,
