irc/jabber/smail: I'll try without screen for a while

Screen does weird things.

$ screen -ls
There are screens on:
        4540.jabberfoo  (Detached)
        4489.jabber     (Detached)
        3959.foo        (Detached)
        1000.mail       (Detached)
        589.irc (Attached)
5 Sockets in /run/screens/S-void.

Now, this one attaches me to "jabberfoo":

$ screen -S jabber -x -R ...some command...

Why?

Running these three apps in screen is a "nice-to-have". If it doesn't
work, well, fsck it then.
