 Hi All,


You can do this easily using the std.net.isemail module:

isEmail returns a struct with the status of the check.
You can use the valid and domainPart to check if it's a valid email 
address for the hotmail domain.

isMail only checks the formatting of the email address and optionally if 
the domain has a MX record.


```
auto e = isEmail("vino.bheeman hotmail.com");

if ( e.valid && e.domainPart == "hotmail.com" )
	...
```

I don't believe MX validation (checkDns) is implemented yet.

btw... yes documentation is an acknowledged issue with regards to 
phobos...but..that aside...it can also be useful (and wise) to 
look at the unit tests in the source code.

I'm not sure that simply calling something you don't know 
anything about is such a good idea these days ;-)

...fortunately, we have access to the source - which gets 
installed with dmd.

or you can find it on github.

test/improve it yourself. but you get the idea....

// ----------------------

module test;

import std.stdio;
import std.algorithm;

/+
CONDITIONS:
     - The domain should contain only "hotmail.com"
     - The email address should contain the symbol " "
+/

void main()
{
     string domainRequired = "hotmail.com";

     string emailAddress = "vino.bheeman hotmail.com";

     auto checkDomain = findSplitAfter(emailAddress, " "); // 
requires import std.algorithm

     //writeln(checkDomain); // Tuple!(string, 
string)("vino.bheeman ", "hotmail.com")

     if (checkDomain[1] == domainRequired)
         writeln("domain ok");
     else
         writeln("invalid domain");


}

Here's another nice option I just found.

Interestingly, I had to disable Avast antivirus, otherwise when I 
compile it, Avast thinks the exectuable is 'suspicous' and 
prevents any further access to it...wtf?

// ---------------------
module test;

import std.stdio;
import std.algorithm;

/+
CONDITIONS:
     - The domain should contain only "hotmail.com"
     - The email address should contain the symbol " "
+/

void main()
{
     string domainRequired = " hotmail.com";

     string emailAddress = "vino.bheeman hotmail.com";

     emailAddress.endsWith(domainRequired) ? writeln("domain ok")
          : writeln("invalid domain");

}

Also you need check that only one   used.
