Mailboxes for standard services, roles, and functions

Recently I encountered an unpleasant situation - the mail server got into spam lists. The hole was quickly found and patched, but Oracle has already put our server on its blacklist, and blocked us at the connection stage.
There was a question - where to write? The site was only a form for customers, support@oracle.com was intended for them.
After some deliberation, the thought appeared - is there a standard that defines the e-mail addresses for which you need to write in this case? It turned out that it is and is described in RFC 2142 .

The most interesting is contained in the tables below.

1. Business information

Address	Zone	Using
INFO	Marketing	Information about the organization, products and services
MARKETING	Marketing	Marketing information and contacts
SALES	Sales	Information related to the purchase of products
SUPPORT	User service	Solutions to problems with products and services

')

2. Network Services

Address	Zone	Using
Abuse	Customer relationship	Complaints about inappropriate content
NOC	Network operation	Network infrastructure
SECURITY	Network security	Security Requests and Bulletins

3. Internet services

Address	Service	Specification
POSTMASTER	SMTP	[ RFC821 ], [ RFC822 ]
HOSTMASTER	DNS	[RFC1033-RFC1035]
Usenet	NNTP	[ RFC977 ]
NEWS	NNTP	Synonym for USENET
WEBMASTER	HTTP	[ RFC 2068 ]
Www	HTTP	Synonym for WEBMASTER
FTP	FTP	[ RFC959 ]

Very often I meet strange addresses in whois or in the communication section on sites, for example, in the RIPE database for my provider, the address is info, and in the RIPN some ancient addresses on mail.ru and support.
Use the addresses from the recommendations at least in the form of synonyms to existing boxes - these are the basics of netiquette.

PS And everything ended well with Orakl, Postmaster answered on the same day and, after explaining the situation, they began to be friends with us again :-)
