Hi Giovanni,
This is indeed an invalid hostname. A hostname must begin with a digit
or letter. (https://www.rfc-editor.org/rfc/rfc1123#page-13)

Hi,
recently I've found this error on my server:
Jun 11 10:46:33 mx smtpd[97386]: 0000000000000000 mta delivery
evpid=aa1ddab63539175b from=<ord...@domain.tld> to=<i...@example.com>
rcpt=<-> source="-" relay="example.com" delay=22h31m25s
result="TempFail" stat="Network error on destination MXs"
The destination domain MX record is:
_dc-mx.140697ab0ac1.example.com which I am not sure is valid but it's
present on the wild.
Is it correct that OpenSMTPD fails to deliver in this case ?
OpenSMTPD version is 7.5.0 running on OpenBSD 7.5.
Cheers
Giovanni
