[logback-user] smtpappender broken in 1.2.9

[Chris Cheshire]

Ceki,

I don't use the maven build system - I downloaded manually from the
repo linked on the download page. Redownloaded this morning and
compared - same files (core & classic) as I downloaded yesterday.

Did the build for 1.2.9 miss a commit?
