Look at this line from the headers above: > Received: from devjbniv2 ([66.130.16.28]) by > VL-MS-MR004.sc1.videotron.ca (Netscape Messaging Server 4.15) > with SMTP id GSXI5005.G09 for ; Wed, 13 Mar 2002 > 15:27:00 -0500 Your server claims to be devjbniv2, which is not a fully-qualified name (it should presumably be something like relais.videotron.ca), and the address 66.130.16.28 can't be resolved. Both of these techniques are used by spammers, and most such messages are spam, so we refuse to accept them. You should fix your MTA and DNS configurations, after which you'll have no further problems. Note that you owe this to your customers: incorrectly configured mail and DNS mean you're not delivering the promised service to them. It also makes you look like spammers, which can result in your being blocked by a number of sites. The message below from your MTA system is completely bogus. Before your mail was rejected, you got dozens of rejections saying exactly what the problem was. Here's an example: Mar 14 00:13:04 wantadilla postfix/smtpd[13300]: 478AB7831F: client=unknown[200.246.179.58] Mar 14 00:13:05 wantadilla postfix/smtpd[13300]: reject: RCPT from unknown[200.246.179.58]: 450 Client host rejected: cannot find your hostname, [200.246.179.58]; from= to= This address (200.246.179.58) is claiming to be Yahoo!, which it most certainly is not: it's spam. Your MTA should return the reason for rejection, and not speculate. I'd recommend that you change the servers to FreeBSD, which are also much more secure than what you're running now.
