hi all, having some obvious dns issues from launching a new website hosted outside of our local domain that has the same url address as our local domain. (http://ourdomain.com
vs mailto someone @ ourdomian.com) I just want to isolate the BES not being an issue. (i'm not convinced it was setup correctly to begin with) I did a simple MX record lookup and retreived the following results:
Banner: besserver.somedomain.com ESMTP ready at Mon, 28 Jan 2008 17:47:43 -0800 [109 ms]
Connect Time: 0.109 seconds - Good

In addition, looking up dnsstuff informs me that the BES is advertising itself as a mail server.
I'm trying to resolve the MX record vs. the DNS record (URL) and then this came up.
there exists a website called mydomain.com (hosted by an external server NOT in the internal domain)
we have an EXCHANGE server that hosts an MX record (somebody @ mydomain.com)
And apparently, the BES is advertising itself as a host?
I am trying to become competent in the area of DNS (study, learn, study)
I more or less understand the implication of the reverse lookup record (PTR)
(please clarify the implication, it would be good for my understanding in a "real world" application)
The thing(s) I forgot to mention! (perhaps not the only thing(s)?) The BES resides on it's own box. The exchange server is also the PDC (1 BDC), the only DNS server. (no backup dns, no secondary dns, no replication....not a good scenario from what i've learned in my studies)
wisdom is awaited with eagerness....
