> It is annoying to have log messages sent to users via SMTP Appender with a static subject, requiring recipients to open each of possibly a vast amount of log emails in order to find out what went wrong.
> Users should be able to insert runtime diagnostic context information to the message text AND to the message subject as well.
> While the first seems to be working with Patternlayout using the mechanism with the %X{<key>} pattern based on a NDC or MDC <key> in the "ConversionPattern" parameter, it does NOT work with the "Subject" parameter with log4j (neither 1.2 nor 2.x), though some bloggers suggest it, e.g. http://stackoverflow.com/a/7015453.
> See http://stackoverflow.com/questions/29435825/log4j2-custom-email-subject-from-map as an example where others found this also.
> This issue should have been fixed long ago.
> I suggest to extend SMTP appender in order to be able to use %X and other Pattern conversion in the "Subject" parameter properly.
> http://openutils.sourceforge.net/openutils-log4j/smtpappender.html
> has already done the part for applying PatternLayout to the SMTP Appender "Subject". I didn't test if this works properly.
> Maybe this work can be included into log4j with minimal effort?
> This feature has originally been realized in LOGBACK using an MDC in Patternlayouts: http://logback.qos.ch/manual/mdc.html
