Opinions?
It would be nice if it could be made usable.
This would tend to make a large organization having all of their servers
helo exactly the same way, which flies in the face of industry BCP (eg:
MAAWG), and even if it wasn't specifically RFC5321-illegal, clearly
violates its intent.
I see nothing wrong if an organization uses the same helo name for all
its mailouts. A helo name does not have to be a label of any DNS
record.
Uh what?
RFC5321:
Section 4.1.1.1:
These commands are used to identify the SMTP client to the SMTP
server. The argument clause contains the fully-qualified domain name
of the SMTP client, if one is available. In situations in which the
SMTP client system does not have a meaningful domain name (e.g., when
its address is dynamically allocated and no reverse mapping record is
available), the client SHOULD send an address literal (see
Section 4.1.3).
...
The SMTP server identifies itself to the SMTP client in the
connection greeting reply and in the response to this command.
Yeah, I suppose you could make all your outbounds have the same name (up
to whatever limit DNS imposes), but clearly this violates the intent.
And it's also very explicitly counter to industry practises/BCP.
