Patch against INN 2.4.1

comment:1 Changed 15 years ago by Julien ÉLIE

Maybe this feature should be added to the check already done on Sender: and From: headers. (This patch currently removes that check.)

Milestone: 2.5.1

According to RFC 5537 (USEPRO):

Contrary to RFC 1036 (Horton, M. and R. Adams, “Standard for interchange of USENET messages,” December 1987.), cancel control messages are not required to contain From and Sender header fields matching the target message. This requirement only encouraged cancel issuers to conceal their identity and provided no security.

The check done on Sender: and From: headers can therefore be removed.

(In [8564]) A patch from Christopher Biedl to alter ARTcancelverify
to check whether at least one group in the cancel message
can be found in the article to be cancelled.

The check for matching Sender: and From: headers is useless
and removed.
