Read Mail loadable module: No way to read other user's personal mail/sent mail (for sysops when deleting a user account, etc.)
For sysops, when deleting a user with the UEDIT command, I've noticed Synchronet gives you the option to read that user's incoming/sent email. When using the "Read mail" loadable module, it appears there's no way to open another user's incoming/sent mail. For the 2nd command-line argument, Synchronet seems to always passe the current user number.
I checked msglist.js to see if it can read another users' email, and it looks like it has the function load_msgs(), so it seems possible. However, Synchronet only seems to pass the current user's user number when running the Read Mail loadable module.
