Are you using Cogent for your BW? If you are, AOL shutoff there peering with Cogent because of all the spammers on Cogent network.

This is what I have been seeing also. Despite my efforts, I have been unable to figure out the ballistics and weighting they are using to generate the algorithm for the timing\duration\trigger for the block. During my testing, while AOL is 'resetting' the connection, one is unable to telnet the SMTP port of their servers from the IP of the mail server(or in some cases, the entire associated subnet). When one tries to telnet, the connection is dropped(reset) within a hundred milliseconds. Telneting may be a nice quick test you can use to find out if AOL dislikes your IP for that brief yet unknown period of time. It turns out that AOL has been doing this for a while now(months), but I have just recently began to see the patterns. And this leads me to believe that perhaps they are keeping archive records of the number of mails sent in a given time from an IP\Domain and then, when they do block, it is for a progressively longer and longer period, relative to the past month's history, or whatever. Here is what you will see in your logs if AOL is 'on your nuts': 12:18 14:17 SMTP-(000003CE) Trying aol.com (0) 12:18 14:17 SMTP-(000003CE) Connect aol.com [64.12.136.121:25] (1) 12:18 14:17 SMTP-(000003CE) rl-recv: connection reset 12:18 14:17 SMTP-(000003CE) 12:18 14:17 SMTP-(000003CE) SMTP_DELIV_FAILED 12:18 14:17 SMTP-(000003CE) >QUIT 12:18 14:17 SMTP-(000003CE) rl-recv: connection reset 12:18 14:17 SMTP-(000003CE) 12:18 14:17 SMTP-(000003CE) requeuing s:\imail\spool\Q337efd002aa.GSC Dave -----Original Message----- From: Mark Brody [mailto:[EMAIL PROTECTED]] Sent: Saturday, December 21, 2002 9:46 AM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] Imail 6.05 Cannot send to AOL.COM I spent 12 hours figuring this one out because a client could not get his newsletter out to most of the 15000 aol email addresses. In a nutshell, AOL is throttling inbound SMTP connections. Not sure how their algorithm works but it slectively drops the SMTP connection (connection reset). It really doesn't appear to have a pattern. They are doing this - presumeably - to prevent spammers from being able to send emails at a rapid rate. The workaround is to go into SMTP in Imail and set retries at 288 and the Queue timer at 10 (minutes). This means that Imail will try to send queued messages each 10 minutes, 288 times (2 days). I figured with all the testing I did, that I can get 600-700 emails per hour out to AOL. I sent sent 2500 eamils to AOL last night and watched the .LST files closely as they went out. It took 36 retries. Your log file will show something like this when it fails (Ver 7.04): 12:18 16:19 SMTP-(00000684) Connect aol.com [64.12.137.184:25] (1) 12:18 16:19 SMTP-(00000684) s: s (or rl-rcv: connection reset in Ver. 7.1+) 12:18 16:19 SMTP-(00000684) 12:18 16:19 SMTP-(00000684) SMTP_DELIV_FAILED 12:18 16:19 SMTP-(00000684) >QUIT 12:18 16:19 SMTP-(00000684) s: s 12:18 16:19 SMTP-(00000684) s: s Hope this helps. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Pete Pesce Sent: Saturday, December 21, 2002 8:18 AM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] Imail 6.05 Cannot send to AOL.COM I have been getting the same thing. It is strange because I can send to certain addresses & Then all of a sudden I cannot send at all. Does AOL put a Temp block if you are sending too many messages to them at once? Please help.
