Just thought that folks would like to know that M$, having embraced the various email protocols (RFC2821, RFC2822, etc), is now in the process of extending them.
I periodically send a bulk email, but individually addressed to each recipient, to about 40 of my most intimate friends advising them of upcoming events at my local LUG. One of the recipients has a hotmail address. This morning's short missive advised about SFD08. The mail addressed to the hotmail account was, for the first time, bounced by M$ Live Mail, with a typically unhelpful message explaining that it was for "policy" reasons that might be related to spam or might be related to a sender's FQDN/dotted-quad mismatch. Since neither the Subject nor the body of the email contained any spam words (unless M$ regards "Software Freedom Day" as a spam expression), the email contained every necessary and sufficient header, and all headers are RFC compliant, I came to the conclusion that the mail suffered from a sender's details' mismatch. Now, my FQDN does not match the dotted-quad address, and does not resolve via lookup, because my IP address is dynamic and my ISP (who is a friend) had never bothered to add my FQDN details his IP range. He is now adding them in -- isn't it nice to have friends. :-) It appears that my email ran afoul of M$'s "Sender ID Framework" (which of course is acronymed to SIDF). Gee, until now I thought that only Dan Bernstein deliberately stuffed up email protocols. But now M$, which hitherto seemed only to stuff up protocols by accident out of ignorance, has joined him. -- Robert Thorsby In /dev/null no one can hear the kernel panic! -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
