Hi Kev,
I think this is actually two problems, so I’ll attack them separately:
User-Agent
FR-3706 - this ticket made optional (default false) the retrieval of the ‘user-agent’ header from JRun when FR logs web requests against a monitored instance. We needed to do this to work around an Adobe bug in the JRun connectors: if they were outdated for the version of IIS/Apache/JRun (i.e. hand’t been recompiled), a “length-of-data” byte read could be misaligned and cause the system to allocate too much memory. An out-of-memory exception would commonly be subsequently thrown.
This UI option did actually make it - it was in FR-5.1.0+ and can be found in Protection > Settings > Email Settings > Show ‘User Agent’ in Email Notifications.
Second problem:
X-Mailer
I don’t remember seeing this one before, and a grep of our codebase doesn’t find it at all. I’ll process it into the issue track (FR-5130) as a new feature request, with the usual caveat that it will have to be triaged into the schedule before we can commit to a release for it. Out of interest, what would you like to have this header set to? What email server are you using that doesn’t allow mail to be sent without it?
Many thanks,
John
