How can I test to ensure that my RDNS is working??? Do I have to have an entry for every domain in reverse DNS??? -Original Message- From: Justin Greene [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 19, 2002 12:18 AM To: CF-Talk Subject: RE: OT: AOL? AOL has their own internal RBL and uses their own rules. If you are sending alot of email across their network you should speak with them about being whitelisted. They may be enforcing rDNS, some anti-spam efforts do this. They probably have other criteria as well. Most of the AOL delivery problems that we have had in the past were just related to a few really slow relays that held the mail for a few hours before spitting it back out. Oh, if they are rejecting based on a non-matching rDNS, they should be doing it at the connection and not even accepting the mail. I would be very surprised to hear that it was really being sent to /dev/null.

How can I test to ensure that my RDNS is working??? dig -x ip.ad.re.ss dig for win32 can be had at ftp.isc.org. or free registration to get to this page: http://preview.samspade.org/t/ or: http://www.dnsstuff.com/ Do I have to have an entry for every domain in reverse DNS??? The critical ones are any ip's that are SMTP clients sending mail to other mail servers. Each sending ip should have matching PTR and A records. Of course, the reverse zone delegation must be done and the delegated NS responding. For all CF or web apps that send mail: 1. the envelope @sender.domain must have A and/or MX records. 2. The MX for @sender.domain must accept mail for [EMAIL PROTECTED] That is, in your CF apps that send mail (and that you want to give the best chance of being delivered), just don't invent any old [EMAIL PROTECTED] You will have no success with MX's that do sender address verification or DNS validations of @sender.domain.

RE: OT: AOL?
That's what I went to. I found just blasting out the mail results in a few getting thru, then the sender is blocked for an indeterminate (but fairly short) period of time. I have a client that's a medical association. They have a large member mailing list with a TON of AOL addresses. I built a mailer that loops over a query and sends an individual email to each recipient AND throttles down the speed of the operation, so as not to flood my mail queue with recipients, or trigger whatever floodgate-alert AOL has in place. Uses cfmail, its query parameter and startrow/maxrows parms. The safe speed I found is disgustingly slow. 10 messages every 17 seconds, and it was important to tie in my mail spool interval (cf admin) to the job. I have a 15 second interval there, so the throttling never doubles up two loads of mail in the queue. Also related is how fast your mail server can send the messages once they arrive in that queue. I also found this to be an issue with msn/hotmail. Throttling the mail solves the problem. You can probably go faster than 10 every 17 secs. Like I said... Disgustingly slow. I just was charged with a guaranteed safe speed and that's what I eventually settled on.

RE: OT: AOL?
AOL has their own internal RBL and uses their own rules. If you are sending alot of email across their network you should speak with them about being whitelisted. They may be enforcing rDNS, some anti-spam efforts do this. They probably have other criteria as well. Most of the AOL delivery problems that we have had in the past were just related to a few really slow relays that held the mail for a few hours before spitting it back out. Oh, if they are rejecting based on a non-matching rDNS, they should be doing it at the connection and not even accepting the mail. I would be very surprised to hear that it was really being sent to /dev/null.

RE: OT: AOL?
Correct. I was going to mention that myself. SMTP-AUTH really checks to see if a sender is an authorized user by matching the username and password with what is in the DB for that user. If it matches, it allows the SMTP traffic to pass. Otherwise, it denies it. This doesn't really have anything to do with RDNS. As for entering everything in the reverse zone, we've tried that. And unfortunately several of those systems that use RDNS to protect against SPAM are not doing so by name (or the HELO listing), but rather by IP. Therefore, we found that unless that same domain (the one in the from header) is the first one that the name server answers to when asked for RDNS, than it will reject it as invalid. | -Original Message- | From: Jason Burnett [mailto:[EMAIL PROTECTED]] | Sent: Wednesday, December 18, 2002 12:25 PM | To: CF-Talk | Subject: Re: OT: AOL? | | | I am not trying to start a flame war here, I just want to | make sure noone gets the wrong impression and confirm or | disprove what I thought SMTP-AUTH was.
