Description

Currently, if Roller installation has any problem in mail provider setting, only following message are logged:

WARN  2014-05-16 16:01:39,233 WebloggerStartup:prepare - Failed to setup mail provider, continuing anyways.
Reason: ERROR connecting to mail server

That is because logging procedure simply discarded the stacktrace:

// setup mail provider, if configured
try {
    mailProvider = new MailProvider();
} catch(StartupException ex) {
    LOG.warn("Failed to setup mail provider, continuing anyways.\n"
            + "Reason: " + ex.getMessage());
}

I think it's not informative. recently I got stucked in mail provider configuration due to this. in my case, the cause was missing intermediate SSL certification. I think it's very difficult to determine that cause without stacktrace or message of parent exception in such case.

I guess some Roller installation may not have mail provider intentionally, so adding stacktrace logging in a verbose level than WARN seems reasonable.
