It's not /you/ you have to worry about it's /everyone else/. Let's say I have an employee who has a MessageOne e-mail address but receives his mail at AOL. I create a CR in the GAL for [EMAIL PROTECTED] and add a secondary address of [EMAIL PROTECTED] If one of your users e-mails him AOL is going to check /your/ SPF record against /my/ forward. And depending on how you've configured your SPF records, it may fail.
So in order for forwarding not to break for your users, everyone else on the planet has to upgrade their servers to be compliant with SPF (regardless of whether or not they choose to implement SPF records of their own). Since there's no announced patch or upgrade for currently shipping version of Exchange, that presents a minor problem for anyone who happens to be running our shared, but rather obscure mailer. Other less obscure mailers have similar issues. Given the snail's pace at which many companies upgrade their mail servers, the time until there's a significant number of mailers who support this is pretty substantial. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:bounce- > [EMAIL PROTECTED] On Behalf Of Paul Hutchings > Posted At: Tuesday, August 24, 2004 1:06 PM > Posted To: swynk > Conversation: SPF Warning > Subject: RE: SPF Warning > > My understanding was that if you do mail forwarding/rewriting SPF can > break > things without - > > http://spf.pobox.com/srs.html > > Paul > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] > > Behalf Of Chris > > Scharff > > Sent: 24 August 2004 12:19 > > To: Exchange Discussions > > Subject: RE: SPF Warning > > > > > > > > > I only have a few domains, we don't do email forwarding/rewriting > > > > It's not a question of whether you do email forwarding/rewriting. > > > > > > > > _________________________________________________________________ > > List posting FAQ: http://www.swinc.com/resource/exch_faq.htm > > Web Interface: > > http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&t > ext_mode=&lang=english > To unsubscribe send a blank email to > %%email.unsub%% > Exchange List admin: [EMAIL PROTECTED] > To unsubscribe via postal mail, please contact us at: > Jupitermedia Corp. > Attn: Discussion List Management > 475 Park Avenue South > New York, NY 10016 > > Please include the email address which you have been contacted with. > > > _________________________________________________________________ > List posting FAQ: http://www.swinc.com/resource/exch_faq.htm > Web Interface: http://intm-dl.sparklist.com/cgi- > bin/lyris.pl?enter=exchange&text_mode=&lang=english > To unsubscribe send a blank email to [EMAIL PROTECTED] > dl.sparklist.com > Exchange List admin: [EMAIL PROTECTED] > To unsubscribe via postal mail, please contact us at: > Jupitermedia Corp. > Attn: Discussion List Management > 475 Park Avenue South > New York, NY 10016 > > Please include the email address which you have been contacted with. > _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
