It's such a confusing problem. Wavelink.com is NOT hosted by gmail.com but my server doesn't seem to care. It simply gave gmail.com wavelink.com's messages. Wavelink.com hosts their own server in-house. I guess the best way I can describe this is that my server doesn't attempt to send out messages to individual servers. What it does is take an e-mail, contact the first server in the e-mail's list of recipients and simply hands off the messages for all recipients regardless of their domain. Almost like some kind of dynamic smart host in that it assumes the first server it contacts is a smart host for it to relay messages through. It's exceptionally weird. Thanks for all your ideas but I've just decided to set up a temporary smart host and once we break for christmas/new years vacation come reinstall everything on the machine. It's gonna suck but at least all my settings will be fresh. -- Ambictus ------------------------------------------------------------------------ Ambictus's Profile: http://forums.techarena.in/members/163907.htm View this thread: http://forums.techarena.in/small-business-server/1282271.htm http://forums.techarena.in

Basically an Exchange (or any other mail server) if authorized to receive mail for a specific domain name, such as wavelink.com, will receive mail for that domain name, provided the MX records are pointing to it, or to an SMTP gateway (whether an appliance device on your network such as Barrcuda Spam Killer, Iron Mail, etc), or if the MX records are pointed to a third part spam solution such as Postini, which then forwards (relays) the email to your server. Now if you are using the SBS POP3 connector, then that means that emails for wavelink.com are being sent to your ISP hosting solution first (the MX records are pointed to the ISP's), and the POP3 connector pulls from the ISP. Good luck with your solution. Let us know if it works after the holidays. Also, curious if you can elaborate on the above. Thanks, Ace

Here's an example of what is happening. An e-mail is sent to user(a)bankofutah.com, user(a)imail.org, user(a)aol.com, user(a)heart.org and user(a)quiznossub.com. Below what I've done is given the IP address of the rejecting server, the user's e-mail address that was rejected and what the IP address resolves to. user(a)quiznossub.com = 64.18.7.10 - s8a1.psmtp.com user(a)heart.org = 166.70.204.242 - exoro-pdc.exoro.com user(a)aol.com = 204.200.196.106 - jibe2.jibehost.com user(a)imail.org = 208.177.146.78 - mailmx.lhmse.com user(a)bankofutah.com = 98.137.54.237 - mta-v1.mail.vip.sp2.yahoo.com So I guess it more seems like there is some SERIOUSLY crosswired DNS going on. However that can't really be the case because if the e-mail was sent to each person individually they would have gotten the e-mail. -- Ambictus ------------------------------------------------------------------------ Ambictus's Profile: http://forums.techarena.in/members/163907.htm View this thread: http://forums.techarena.in/small-business-server/1282271.htm http://forums.techarena.in

Is it wavelink.com? And what is the IP address of YOUR mail server that is supposed to send email? I want to do a little more research in this for you. I already know the MX records, if it is wavelink.com, however I need to know where mail is being sent from. If it is being sent from your IP address at your office, but the MX records are elsewhere, then what may be happening is you do not have an SPF record that indicates your IP is authorized to send mail from your IP, therefore NUMEROUS receivers are rejecting it because of this.
