On the command line, I key: MMAIL/EMLSTMF2

Where does the command magically get my email address? Can I use a
RTV type command to grab this myself?

E-mail stream files (EMLSTMF2)
<<SNIP>>

'Sender's e-mail address' . . . 'Joel.Stone@xxxxxxxxxx'

The request to DSPCMD MMAIL/EMLSTMF2 will presumably show that there is a "Prompt override program" (PMTOVRPGM parameter; on CRTCMD and CHGCMD) defined for that *CMD object.

Whatever that named program does, is how the value is provided for the pre-filled "Sender's e-mail address" parameter. That program may obtain the information in the "directory" (WRKDIRE) information. Perhaps using the following:

Search System Directory (QOKSCHD) API
http://publib.boulder.ibm.com/infocenter/iseries/v6r1m0/topic/apis/QOKSCHD.htm

To obtain what the command's prompt override program will effect, rather than doing the work [perhaps based on an assumption of what] that Prompt Override Program would do, then perhaps using the following:

Retrieve Prompt Override (QPTRTVPO) API
http://publib.boulder.ibm.com/infocenter/iseries/v6r1m0/topic/apis/qptrtvpo.htm
