Syntax public StringDictionary GetExtensions()
Public Function GetExtensions As StringDictionary
Return Value
Type:
StringDictionaryThe key-value list of the server capabilities, or a null reference
(
Nothing in Visual Basic) if the capabilities list is not available.
Exceptions Remarks
In order to use this method, the connection with the SMTP server must already
be established, and
Hello method already called.

---|
If the server does not support EHLO command (i.e. the server is not ESMTP enabled),
the capabilities list will not be available. |
In the returned StringDictionary,
each key is a capability name (always lowercase). Its value is either empty string
(if the capability has no parameters) or space-delimited list of the parameters.
Examples This sample displays the list of all capabilities supported by the server.
