У меня на сервере smtp есть письмо для отправки с адреса postmaster@test.testone.aws.
Находясь на сервере в журнале просмотра событий такая ошибка:
The system failed to register host (A or AAAA) resource records (RRs)
for network adapter with settings:
Adapter Name : {C7BAFAFE-DBF4-4C76-B406-8A25283E4CF9}
Host Name : test
Primary Domain Suffix : testone.aws
DNS server list :
172.20.2.184, 172.20.1.26
Sent update to server : <?>
IP Address(es) :
172.20.0.245
The reason the system could not register these RRs was because the DNS server failed the update request.
The most likely cause of this is that the authoritative DNS server required to process this
update request has a lock in place on the zone, probably because a zone transfer is in progress.
You can manually retry DNS registration of the network adapter and its settings by typing
'ipconfig /registerdns' at the command prompt.
If problems still persist, contact your DNS server or network systems administrator.
Может быть, вы знаете, с чем это связано?
