[logback-user] Hostname in SMTPAppender subject

[Mayes, Christopher]

Hi, there.

Is there a way to get the reporting machine's hostname into the subject of the SMTPAppender's email address?   According to a blog post, (http://blog.spiralarm.com/richard/2007/10/watching-production-logs.html) you can do something like this for log4j:

<param name="Subject" value="[SMTPAppender] ${user.name}@${hostname} error message" />

Is there a Logback equivalent?

Thanks,

-Chris
