lists! It is very annoying to discover that someone has gone on vacation and find a vacation message for every message they've received. Mailing list administrators: this is a good example of why it is bad practice to force the Reply-To: field of mailing list messages to that of the list submission address.

The format of Usenet news messages is specified in RFC-1036, 'Standard for interchange of USENET messages.'

There may be a difference between the groups that exist at your site and those that your site is willing to receive. For example, the subscription list might specify comp.all, which should send all newsgroups below the comp hierarchy, but at your site you might not list several of the comp newsgroups in the active file. Articles posted to those groups will be moved to junk.

The article's date of arrival is kept in the middle field of the history line and given in seconds since January 1, 1970.

I don't know why this happens, but it does from time to time.

I wouldn't try this on the Internet, either.

When posting an article over NNTP, the server always adds at least one header field, NNTP-Posting-Host:. The field contains the client's hostname.

The same problem exists with the Simple Mail Transfer Protocol (SMTP), although most mail transport agents now provide mechanisms to prevent spoofing.
