Hello,

I use logback-0.9.18 and slf4j-1.5.11

At SMTPAppender, I want to encode in the designated charset using parameter 'CharsetEncoding'.
I set to look at the manual as follows.
(manual:http://logback.qos.ch/manual/appenders.html#SMTPAppender)

<configuration>
<appender name="EMAIL" class="ch.qos.logback.classic.net.SMTPAppender">
<SMTPHost>smtp.gmail.com</SMTPHost>
<SMTPPort>465</SMTPPort>
<SSL>true</SSL>
<Username>YOUR_USERNAME@gmail.com</Username>
<Password>YOUR_GMAIL_PASSWORD</Password>
<To>EMAIL-DESTINATION</To>
<From>YOUR_USERNAME@gmail.com</From>
<BufferSize>4</BufferSize>
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>%date %-5level %logger

- %message%n</Pattern>
</layout>
<CharsetEncoding>ISO-2022-JP</CharsetEncoding>
</appender>

<root>
<level value="ERROR" />
<appender-ref ref="EMAIL" />
</root>
</configuration>

I look at outgoing mail as follows.
Charset is not "ISO-2022-JP" !!

------=_Part_0_26281671.1268558498468
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

-----=_Part_0_26281671.1268558498468-

'Encoding' 'CharsetEncoding' instead of using as follows, the result is the same.

<appender name="EMAIL" class="ch.qos.logback.classic.net.SMTPAppender">
....
<Encoding>ISO-2022-JP</Encoding>
....
</appender>

Could you confirm it?
