Mail yang ini diterima dengan baik.
Kalau recipient tidak menerimanya di mailboxnya, periksa ke routing log.

Mail tidak dibedakan berdasar sender/recipient atau subject tetapi berdasar
message-ID

https://en.wikipedia.org/wiki/Message-ID

-- quote -->
Message-ID is a unique identifier for a digital message, most commonly a
globally unique identifier used in email and Usenet newsgroups.[1]

Message-IDs are required to have a specific format which is a subset of an email
address[2] and to be globally unique. That is, no two different messages must
ever have the same Message-ID. A common technique used by many message systems
is to use a time and date stamp along with the local host's domain name, e.g.,
950124.162...@example.com.[3] On the other hand, if two messages have the same
Message-ID, they are presumed to be the same one and one version is discarded.
But, as Google MTAs (message transfer agents) mangle the ones of Outlook,
several same messages may coexist with original and mangled ones and create
problems in referencing each other for threading[citation needed].

Message-IDs, if present, are generated by the client program sending the email
(mail user agent, or MUA) or by the first mail server (mail submission agent, or
MSA).[4]
