I have to agree with John here - I've been sending back 'email me at [email protected] if this in an error' for all rejections here since 2003 or so, and can count the legit mail to postmaster I've received in that time on one hand, maybe two; the stuff that gets rejected before the accept postmaster default gets a different error, containing a phone number. I've never had anyone call me there. Not that it bothers me much - I've done my part, I figure, and if they aren't willing to email a postmaster or call, then <shrug>? What can I do? I'll add that even if everyone were willing to email/call with problems, the hideous things that (e.g.) Exchange does to your carefully handcrafted rejection errors are enough to cripple the least tech-savvy of your likely audience, anyway. -- hesketh.com/inc. v: +1(919)834-2552 f: +1(919)834-2553 w: http://hesketh.com/ antispam news, solutions for sendmail, exim, postfix: http://enemieslist.com/
