Potential Virus or System Message?

[Faithful John <whureu@gmail.com>]

Hi,
I got this weird message, when I left my email through Telnet/Pine
running when I left my house.

Of course, nothing happened... at least I'm pretty sure (I'm a
relative newbie, therefore don't have a great understand of all things
Linux).   Is this normal?   should I be concerned?   Is something in
my system that I should get rid of?

I'm currently running Testing on XFree86, on a pentium classic Aptiva
computer (from 1996).      Any info I can get would be helpful.  
Thanks.
