check email addresswhat happens when the nslookup for mx records turns up a mail server that
belongs to the isp and not the actual mail domain of the company whose email address i want to check as valid? I want to know this in relation to nslookup; i know about other email check tools on the web. forgot to mention that i want to check with telnet sessions for this but if
there is no mail domain directly for that domain how can i use telnet for checking smtp etc?

If you do an nslookup to find the MX records for the domain, you're going to find.....the MX records for that domain. If joebloggs.com is using Earthlink for its mail servers, that's what you're going to see. nslookup isn't meant to check valid SMTP addresses. It just queries DNS. > Have I misunderstood you?

(mail1.e-access.com.au) not the domain itself.

Check what, exactly? You can try sending an email message to the purported recipient's SMTP address in a telnet session. What are you trying to do? > the mx was for Again, what exactly is it you're trying to do? You cannot check the validity> the isp (mail1.e-access.com.au) not the domain itself. of an email address by using nslookup. If the domain you're trying to look up uses the ISP's mail servers as its MX records -- well, of course nslookup will tell you that.
