I love RFCs. http://www.ietf.org/rfc/rfc2821.txt % lynx -dump http://www.ietf.org/rfc/rfc2821.txt | grep -C2 'refuse to accept' An SMTP server MAY verify that the domain name parameter in the EHLO command actually corresponds to the IP address of the client. However, the server MUST NOT refuse to accept a message for this reason if the verification fails: the information about verification failure is for logging and tracing only. > This will be a problem with a few services, AOL for example.

Not good company to be with. http://www.cio.com/article/149250/4 It's known as Black Wednesday, August 10, 1996, the day all of AOL's routers went down, and no one could get any packets to our systems - they all just got thrown away. --snip of how mail servers crash when combined TCP timeouts are longer than queue re-run timeouts-- Well, that's what happened, and I [Brad Knowles] was personally blamed for taking out all Internet e-mail across the entire world. > In fact my own server will not accept mail from "UNKNOWN" hosts ( it > resolves the hostname, then resolves the IP PTR, and compares the > hostname and the resulting PTR record ) Please fix your mail host.

I disagree. The RFC disagrees. -john -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
