When building on the master and there are more than one user that made a submission, the perforce plugin is able to determine the email address of all the users except one.

I have made submissions as two different users (scm and cwong). Regardless of the order that the submissions are made, the email address for cwong could not be found.

For another build, seven different users had made submissions (scm, cwong, johara, pt, cblank, and ajerjiss). For this build, the plugin was able to determine the email addresses for each of the users except "pt".

Here is a copy of the stack:
