Smtp email programming question (but not really)

This is not really a programming question but I can move it there.

I am trying to automatically send email using programming using WCF and web services. Some links below that are self-explanatory even if you don't code, see below at Reference "A".

I want to do this for non-SPAM purposes (for password recovery for a program I wrote). I understand some commercial webhosts actually will not allow these type programs on their servers, for anti-spam reasons, but in this case I don't intend to spam and anyway I'm sure there are other remedies if I do spam that DASP can resort to.

I need to know my smtp.HOST, see below on what I did, at reference "B", and my smtp.PORT, see below at "C"

Finally I need to know if anybody has done this before at DASP or if it is permitted--I think 99% sure the answer is yes.

Specifically, I need to please know:

1) if the procedure in REFERENCE "B" will yield an accurate IP Address number that corresponds to DiscountASP.Net smtp email servers

2) if the default smtp port for email is: smtp.Port = 25;

3) the User Name and Password I think I can figure out: it's something you create online using the email manager tool at: https://my.discountasp.net/email-manager/default-sm.aspx

Thank you,

SmtpClient smtp = new SmtpClient();

smtp.Host = "111.111.111.111"; // Replace with your servers IP address //??What is it for my DASP account?

smtp.Port = 25; //is this true for DiscountASP?

/////// REFERENCE "B" ////////////
0. Entering my SMTP Server information from the DiscountASP Control Panel

1. Using this tool: http://www.hcidata.info/host2ip.htm (is this a reliable tool)?

2. Gives me this: sm07.internetmailserver.net -- is this a DiscountASP.net server?

And a certain IP domain name 64.XX.ABC.123 that corresponds (says the website above) to smtp.MyDomainName.com

////////// REFERENCE "C" /////////////
smtp.Port = 25; //is this true for DiscountASP?
