Mail Server & DNSSTUFF tests

Ok so I have two domains I'm using at the moment. As far as I can tell, both domains have their MX records set correctly, as entering the url and sending mail to both give expected results. However, with I do a check via dnsstuff.com, and using the dnstools, I get a big red error message: ERROR: I could not complete a connection to any of your mailservers! MAIL.digitalmc.tv: Timed out [Last data sent: RCPT TO: ] If this is a timeout problem, note that the DNSreport only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain. Now, the deal is I'm getting mail, and most of it comes in pretty quickly, although some of it does take a very very long time. In the GUI, I have the SA>Mail>General tab, the domain name is set to mail.domain.com, and the host name is mail.domain.com (I've tried diferent combinations of both mail.domain.com and domian.com... none seem to solve the problem) In the GUI, SA>Advanced>Hosting>Local Hosts Aliases, I have domain.com, and localhost. I'll worry about the other domains later, but if I could just get this problem solved, the rest I think I could figure out. If there is any thing glaring apparent, please let me know so I can hopefully put my mind at ease. Much Thans In Advance. J
