RE: [IMail Forum] Mail server connections mysteriously dropping

[Panda Consulting S.A. Luis Alberto Arango]

My guess: The remote domain is running an antispam application. The sender domain or your IP is in their blacklist and it just drops your connection.     It happens to one of my clients a while ago. It took us a while to figure that out.   Luis From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Lester Brown Sent: Friday, November 12, 2004 1:10 PM To: [EMAIL PROTECTED] Subject: [IMail Forum] Mail server connections mysteriously dropping   I'm having trouble sending e-mail to several domains for some reason. I've talked to the people on the receiving end, and they say that their mail server isn't recording any connections in their server log at all.  Here is a snip from our server logs of a transaction to one of the servers we're not able to send to.   We’re able to send and receive normally to most other people, though, so I’m not sure why these connections aren’t going through.   11:09 08:22 SMTPD(eeae00390080f3f5) [169.204.236.4] connect 169.204.236.240 port 4709 11:09 08:22 SMTPD(eeae00390080f3f5) [169.204.236.240] EHLO LesP4 11:09 08:22 SMTPD(eeae00390080f3f5) [169.204.236.240] MAIL FROM: <[EMAIL PROTECTED]> 11:09 08:22 SMTPD(eeae00390080f3f5) [169.204.236.240] RCPT TO: <[EMAIL PROTECTED]> 11:09 08:22 SMTPD(eeae00390080f3f5) [169.204.236.240] E:\IMAIL\spool\Deeae00390080f3f5.SMD 10202 11:09 08:22 SMTP-(eeae00390080f3f5) processing E:\IMAIL\spool\Qeeae00390080f3f5.SMD 11:09 08:22 SMTP-(eeae00390080f3f5) Trying ThomasFallonArchitect.com (0) 11:09 08:22 SMTP-(eeae00390080f3f5) Connect ThomasFallonArchitect.com [207.61.90.202:25] (1) 11:09 08:22 SMTP-(eeae00390080f3f5) 220 mailforward.freeparking.com ESMTP Exim 4.41 #1 Tue, 09 Nov 2004 11:22:20 -0500 11:09 08:22 SMTP-(eeae00390080f3f5) >EHLO mail.washougal.k12.wa.us 11:09 08:22 SMTP-(eeae00390080f3f5) 11:09 08:22 SMTP-(eeae00390080f3f5) >HELO mail.washougal.k12.wa.us 11:09 08:22 SMTP-(eeae00390080f3f5) 11:09 08:22 SMTP-(eeae00390080f3f5) SMTP_DELIV_FAILED 11:09 08:22 SMTP-(eeae00390080f3f5) >QUIT 11:09 08:22 SMTP-(eeae00390080f3f5) 11:09 08:22 SMTP-(eeae00390080f3f5) Trying PDT (1) 11:09 08:22 SMTP-(eeae00390080f3f5) ERR no address "PDT" 11:09 08:22 SMTP-(eeae00390080f3f5) requeuing E:\IMAIL\spool\Qeeae00390080f3f5.SMD R0 T1 11:09 08:22 SMTP-(eeae00390080f3f5) finished E:\IMAIL\spool\Qeeae00390080f3f5.SMD status=3     Anyone have any ideas?  I've applied all of the updates to iMail and we're at version 8.13.   TIA,   Lester Brown Network Support Specialist Washougal School District 112-6
