Hello all, I need to tap the collective here. We are currently running a production I-mail 6.06 server, and have a I-mail 7 server in buildup. We wish to use SSL connections exclusively, but we are having some customers who are consistently getting "Page cannot be displayed" errors as soon as they accept our I-mail self signed certificate. We have enough of them that it's not a single isolated incident, but we also cannot reproduce the error. They are running the correct version browser, their browser settings are set to medium, we are running SSL on port 443, and there does not appear to be a single ISP that is causing this. I am close to stumped here. Does anyone have any ideas to offer on why some people cannot connect with SSL, but connect fine unsecured, and some people have no trouble either way? We are running the KWM Templates, though I understand that that's not really relevant to the SSL issues...

I set up a list server for an Imail user in LaLaLand, his customer sent 175k msgs, with 1000's to earth sometthing or other. boom, all their MX's started refusing with "unknown user" but if you telnetted from another ip, sent mail to the unknown user, it was accepted. >Is it possible that Earthlink is doing a reverse DNS lookup on domains that >send email to their server? anything's possible. >I currently do not have proper PTR records that doesn't help, >, 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). telnet to the MX from an ip different from your Imail ip to see if they've blacklisted imail's ip.
