no, there is no way of checking. SMTP is *not* like http at all - it's like sending a 'real' letter - you can't tell if the user will open it with an elegant paper knife or just tear it open with their teeth<BR><BR>j
Haha! Good answer! Apparently people like MessageMedia.com send a plain text and HTML version in the same first email. The HTML also includes a single pixel graphic (suitably tagged) which will ping the server and get flagged as 'Yes' in the database.<BR>Can kind of figure the pinging bit, but how to do the two part email has got me stumped.
here's an idea.<BR><BR>the graphic is actually an ASP file in an <img src="email@example.com" /> tag. when the page loads, it logs to the database that the client is HTML capable - information which can then be re-used in future, then response.redirects to the real image file.<BR><BR>easy.<BR><BR>I thought you were looking for an immediate means of detecting, rather than a longer-term solution<BR>
Alright! Looks like a pretty smart way to do it. Didn't know you could do that in an img src. I'm relatively new to ASP so I'll need to figure out how to log the field to the database but really appreciate your replies!
