Well, the reason for using the RCPT callback is because a lot of
spammers use false addresses in the from: line... Some even use domains
that don't exist. Much less invalid users. Even a later bounce would
cut the spam by 50% or more.

Look at Callbacks. And remember that several situations (like a mailhub
setup, or by default in certain mailservers) the mailserver might accept
EVERYTHING you throw at it with 250 ok and generate the bounce
afterwards.

Do you long for a change of the default font at boot up ? Look at the
kbd fonts in /usr/lib/kbd/consolefonts installed by the "kbd" package".
man setfont for details ... You may  prefer to include the line in
your.bashrc ... Try : $setfont /usr/lib/kbd/consolefonts/b.fnt.gz
