• Rebex.Common.dll
• Rebex.Networking.dll
• Rebex.Mail.dll
• Rebex.Smtp.dll

There is no need to install, configure or distribute anything else to make them work.

Fine-tuning client behavior 

The Smtp object make it possible to adjust various client settings and workarounds. Most of them are available through Settings property (see the next section for details).

Some settings are available at the Smtp object itself. This includes the Encoding property that specifies a charset to be used when encoding commands and decoding responses. However, since all of those should normally use ASCII, changing the default value is seldom needed.

// create client instance
// ...

// set encoding to UTF-8
client.Encoding = Encoding.UTF8;

' create client instance
' ...

' set encoding to UTF-8
client.Encoding = Encoding.UTF8

The common settings include a Timeout property as well. Use it to change the default timeout value of 60,000 milliseconds.

Workarounds for common server issues 

Workarounds for some server issues are not enabled by default because detecting them automatically would be troublesome. They can be changed through properties of Smtp.Settings object.
