First, the "biggies" (earthlink, hotmail, yahoo) often have problems, and it can often take hours or even days for mail to get there. The problem here is that IMail's bounce messages don't provide much useful information -- it would be *great* if they would include the response from the remote mail server. For example, when we get blacklisted in the spam databases (since we intentionally run an open relay, even though spammers can't get mail out through it), IMail bounces mail we send with "unknown user" (which makes it sound as though the user we are sending to doesn't exist). If it put in the "550 You are blacklisted at wherever..." response, we would immediately know that there was a problem on our end. But, you can just look at the SMTP log file to find out what Earthlink is saying. >Is it possible that Earthlink is doing a reverse DNS lookup on domains that >send email to their server? Yes, it is possible. http://mail.declude.com/tools/ptr.ch?ip=207.114.212.205 shows that you have no reverse DNS entry (you can go to http://www.declude.com/tools and use the "Reverse DNS Tester" to get there). >I currently do not have proper PTR records, as >I only have a small block of IPs, and I'm having problems getting my >provider to delegate authority to my DNS servers (please excuse me if my >teminology is wacked, I'm not a real DNS guy). Don't worry too much about the terminology, reverse DNS is a big mystery for a lot of people, even people who know standard DNS pretty well. Feel free to E-mail [EMAIL PROTECTED] to ask about getting the delegation set up; or, you could have them add your IPs to their DNS servers which might be easier. -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
