Sad, but true:
Until we have firm laws in place, I've taken the law in my own hand, and since July 4, 1997 (rebel day!) I am using a program that filters my incoming email, mostly to get rid of junk email (a.k.a. SPAM). It is thus possible that I will be delayed in responding to some email sent to me, depending on your content :-) I like personal and professional mail, or even commercial mail I have requested, but all bulk, block and spam email is junked or reviewed when I feel like cleaning up.
If for some reason your mail is bounced because you are not on my white-list, here's a way to request your email to be whitelisted:
In particular, my list of blacklisted domains is now available for any search engine.
If you want to read more on why and how I did it, here is a sample reading list:
By US Code Title 47, Sec.227(a)(2)(B), a computer/modem/printer meets the definition of a telephone fax machine. By Sec.227(b)(1)(C), it is unlawful to send any unsolicited advertisement to such equipment. By Sec.227(b)(3)(C), a violation of the aforementioned Section is punishable by action to recover actual monetary loss, or $500, whichever is greater, for each violation.
