A quick Google on search term "freeware smtp object" returns a few components like this:

Most of these are purely for sending mail, and some will obviously have more properties and methods than others. Depends whether you want to send mail or query for some other response (what else can you do?)
Perhaps I've misinterpreted your requirements (and this is why you should be specific when posting to any forum, not just this one), but I suspect that since such objects as you appear to have requested can be found on Google in a matter of moments, the elder statesmen of the board felt that your search should be more... how can I put it? Self-motivated?
Not that I'm defending their somewhat curt response either. I share your feeling that such responses were probably not worth the time it took to type them without some clarification, but also can't condone your slightly snappy response, your previous with Jens notwithstanding.
Have searched Google also for "telnet objects" but the returns thus far (have only looked at two of them) seem to be either clients or servers and are not actually COM-able.
Hope you find what you need - failing that consider Perl if this is purely for your own use, and won't become too complicated in distribution.
