In other words, e-mail is going out addressed from me, using my e-mail address, but not really <i>from <\/i>me.  It&#8217;s technically not that difficult to do, and is akin to someone sending out junk mail (you know, the paper kind) with the return address label picked at random from a phone book.<\/p>\n<p>In other words, there are any number of people getting e-mail from me offering to increase (or decrease) the sizes of various things on their body, to provide them with prescription-free pharmaceuticals, and to describing various hot stock (or video) picks.<\/p>\n<p>Swell.<\/p>\n<p>The biggest danger from spoofing is being blacklisted &#8212; having ISPs or services that they turn to decide that &#8220;this address (or even this domain) is being used for unscrupulous purposes, so we&#8217;ll simply block all mail from it.&#8221;  While most blacklist operators dig a bit deeper than just e-mail addresses (given the increasing prevalence of spoofing), not all of them do, so there is a real danger there.  And, alas, there&#8217;s not much I can do about it, unless I discover that I&#8217;ve been blacklisted and can then appeal to whatever powers that are.<\/p>\n<p>Harrumph.<\/p>\n<p>Anyway, an object lesson.  Don&#8217;t just assume the return addresses (and\/or names) on those spams you receive are actually the folks involved.  They probably aren&#8217;t, in fact, and by using your e-mail client to block them from ever again darkening your virtual door, you may be shutting out someone who will need to contact you some day in the future.<\/p>\n<p>Like me.
