Lets see if I understand you correctly. Your Internet service is provided by Quest. However Quest will not provide you with an email account? (I would think that very odd). And you have yet another third party Internet provider, through whom you do have an email account? If I understand you correctly as stated above. Then you can of course receive mail with your third party ISP mail server. However to send email you will need to do so through your Quest mail server. But they are not providing you a server? Ok, then you must return to your third party ISP and tell them Quest does not provide you with a mail server. And so you must use the third party's mail server instead and they need to allow relaying on their server from the Quest domain for your account with them. Good luck with that happening. The problem is not Apples Email client your using and there is no setting to help you out. Since all responsible ISP's refuse relay access through their servers. And since Quest doesn't provide you a mail server on their domain, then your kind of stuck if the third party won't allow you to relay or if Quest won't allow you access to their mail servers. So you have a few solutions that are possible. A) Use a web mail interface provided by your third party ISP for all of your outgoing mail. B) See if your third party has an IMAP server you can use instead of a SMTP mail server C) Install your own mail server and purchase a static IP along with a domain name. I hope I understood your problem clearly Kristen On Nov 12, 2006, at 5:33 PM, russells at strodtbeck.org wrote: > > I use Apple's Mail application for mail..I recently signed up with > Quest.com DSL internet.
