AspEmail.com -- AspEmail.NET Object Reference

Specifies an alternative text version of a message while Body specifies an HTML version. When this property is set, AspEmail.NET generates a "multipart/alternative" message to support email clients that are not HTML-enabled. Side effect: when this property is set, IsHTML property gets set to True.

This is a premium feature.

string Body (Read/Write)

Specifies a message body. Can be in a text or HTML format. In the latter case, the IsHTML property must be set to True.

string CharSet (Read/Write)

"ISO-8859-1" by default. Specifies the charset part of the Content-Type MIME header. Setting this property to a non-default value causes AspEmail.NET to perform a conversion of message body characters into the specified character set. If this property it set to "UTF-8", AspEmail.NET uses the UTF-8 encoding. To learn more, and for a list of valid values for this property, see Section 2.1.4.

This is a premium feature.

string ConfigPath (Read/Write)

Returns the location of the current configuration file. This property was introduced in version 5.3.0.3127 and is useful when the component is used in classic ASP.

string ContentTransferEncoding (Read/Write)

"7bit" by default. Specifies the Content-Transfer-Encoding MIME header for the message body. Other valid values include "8bit" and "quoted-printable". If you set this property to "quoted-printable" AspEmail.NET will automatically convert the message body to the Quoted-Printable format as specified in RFC-2045. You should always set this property to "quoted-printable" if you set CharSet to "UTF-8".

This is a premium feature.
