Anything written in 1989 or 1990 can't be a variation of Randal's sh2perl, which he wrote in 1998 for an April's Fool joke. See the Changes file or The Perl Timeline. Do you have references for the email you dredged up?
As far as I know, there wasn't a script that would automatically email things to Tom. Early on, his email address got passed around as a csh to Perl translator. Supposedly, Tom would send back Perl versions, although I have yet to meet anyone who used this service.
Chris Nandor beat sh2perl by a couple months with D'oh, which you should write with the old package notation instead of the double colon.
