Well I ran my domain (familycareintl.org) against several rbl's and I DO have RDNS records and didn't find anything amiss.
How/where did you determine ( for future reference) that our server " asked for their Mx records, didn't get them so connected to the A record for iwhc.org" I don't see where in the logs you picked that up thanks -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chris Scharff Sent: Wednesday, August 13, 2008 5:58 PM To: Exchange Discussions Subject: RE: 550+5.7.1+Unable+to+relay+for Are you responsible for the iwhc.org domain? http://www.intodns.com/iwhc.org They have some DNS problems. In the instance below it appears Exchange asked for their Mx records, didn't get them so connected to the A record for iwhc.org which is not configured to accept mail for the domain. There's not a problem with Exchange and the 550 errors are not being generated by your server. I guess you could have DNS problems as well, but there's no evidence of that in the sample you provided. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jean-Paul Natola Posted At: Wednesday, August 13, 2008 4:22 PM Posted To: swynk Conversation: 550+5.7.1+Unable+to+relay+for Subject: 550+5.7.1+Unable+to+relay+for Hi all, I've been seeing these rejections a little more frequent than before, I have logging turned up on the SMTP server and all it tells me is basically what the NDR says- There is no consistency as to who the sender is or the recipient- it just randomly happens , unfortunately the randomness is now occurring to upper management :(. 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionResponse SMTPSVC1 FCI-EX - - 250-web02-ctsg.ctsg.com+Hello+[68.167.21.154] 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionCommand SMTPSVC1 FCI-EX - MAIL FROM:<[EMAIL PROTECTED]>+SIZE=81162 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionResponse SMTPSVC1 FCI-EX - - [EMAIL PROTECTED] 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionCommand SMTPSVC1 FCI-EX - RCPT TO:<[EMAIL PROTECTED]> 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionCommand SMTPSVC1 FCI-EX - RCPT TO:<[EMAIL PROTECTED]> 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionResponse SMTPSVC1 FCI-EX - - [EMAIL PROTECTED] 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionResponse SMTPSVC1 FCI-EX - - [EMAIL PROTECTED] 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionCommand SMTPSVC1 FCI-EX - RSET - 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionResponse SMTPSVC1 FCI-EX - - 250+2.0.0+Resetting 0 SMTP - - 2008-08-13 20:38:15 64.209.141.12 OutboundConnectionCommand SMTPSVC1 FCI-EX - QUIT - 0 SMTP - - 2008-08-13 20:38:17 64.209.141.12 OutboundConnectionResponse SMTPSVC1 FCI-EX - - 221+2.0.0+web02-ctsg.ctsg.com+Service+closing+transmission+channel 0 SMTP - - Windows server 2003 exchange 2003 - XP client with outlook 2003 sending from within the LAN - On the SMTP server I have checked off "allow all computers which successfully authenticate to relay , regardless of the list above" Thanks JP _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
