Message-ID: <20020107103929.F15302-100000@bsd1.nyct.net> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hi, I'm using the default freebsd.mc to build my sendmail.cf. The default FreeBSD sendmail configuration allows people to send spam through it using this style of e-mail address: "me@remotedomain.com"@localdomain.com As long as your mail server accept mail for localdomain.com then it will relay the message for you. This should probably be corrected in FreeBSD's default sendmail configuration, but I'm not sure where to even start. Oh yeah, this is on FreeBSD 4.4-STABLE built Dec 7, 2001. Thanks. -- Eric Futch efutch@nyct.net http://www.nyct.net/~efutch KNYC: 07-Jan-02 07:51 EST: 36.0 F (2.2 C), overcast, humidity 92% To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
