C# .NET 1.1 SendMail

October 28, 2010

Heres how ya send HTML with attachment in .NET 1.1

Believe .NET 1.1 comes pre-installed on all 32 bit machines

What this does is creates a rar archive with 123.txt in it, then emails it out

Depending upon what your ISP is, you will need to change the SmtpServer variable

Multiple recipients need to have a ; in between em

.NET Framework 1.1 is no longer supported through Express C# 2002-2003

You'll need to install the .NET Framework 1.1 Redistributable and .NET 1.1 SDK

This has to be compiled from commandline with

csc /out:c:\smtp.exe Program.cs

or if you want no console window

csc /target:winexe /out:c:\smtp.exe Program.cs

Directory should be %windir%\Microsoft.NET\Framework\v1.1.4322

that 1.1.4 could be different as long as it says 1.1.x

try to implement dnsresolve and gethostname as an update later on...

in order to use nslookup from .NET to grab the hostname to the smtpserver variable

                msgMail.Attachments.Add(attachment);                
                SmtpMail.SmtpServer = "smtp.comcast.net";
                SmtpMail.Send(msgMail);            }            catch (Exception e)
            {
                System.Console.WriteLine(e);
                System.Console.Read();
            }
        }
    }
}

and after a format reload upon a XP Home Edition OS, the .NET Framework 1.1 was NOT pre-installed. It was an optional software update

And you dont need to download the SDK if you choose to install the optional software

I stand corrected

okay.. so this goes out to whats my ip

grabs the ip dns lookup upon the IP

uses index functioning to try each variable until it reaches the smtp server needed

and uses threads to get its work done

and send email out all while bypassing ZoneAlarm with sendkey A-A

shoulda used a kernel driver but.. thats for later

yea, i grabbed some code from a couple of places to help me gettttteerrrrrr done...
