Ok, heres a report from network-tools Interestingly, the address it picks up for our mailgate is wrong, its our old one about 10 days ago we switched from 62.49.146.170 to 80.176.164.194
If I do an nslookup - set type=mx - partition.co.uk Then it gives me the right gateway, can you possibly try for me and see what you get? It might explain why our non-delivery of mail is intermittent (though only 1 in 30 will get through, for example) Can anyone decipher this for me? canonical address: <[EMAIL PROTECTED]> MX records preference exchange IP address (if included) 10 mailgate.partition.co.uk [62.49.146.170] **** <<< this is the old mailgate address 100 relay-1.mail.demon.net [0.0.0.0] 100 relay-2.mail.demon.net [0.0.0.0] SMTP session [Contacting mailgate.partition.co.uk [62.49.146.170]...] [Timed out] [Contacting relay-1.mail.demon.net [194.217.242.51]...] [Connected] 220 relay-1.mail.demon.net ESMTP Thu, 11 Dec 2003 19:50:01 +0000 EHLO Network-Tools.com 250-relay-1.mail.demon.net Hello Network-Tools.com [66.46.181.116] 250-SIZE 250-PIPELINING 250 HELP NOOP *** See <http://www.hexillion.com/MailAdmin/> for an explanation of this session 250 OK NOOP *** HexValidEmail COM 1.2 <cb2dc578f9be810f7d54402a66c0b818418f456f> 250 OK RSET 250 Reset OK VRFY support 252 Administrative prohibition RSET 250 Reset OK EXPN support 550 Administrative prohibition RSET 250 Reset OK MAIL FROM:<[EMAIL PROTECTED]> 250 OK RCPT TO:<[EMAIL PROTECTED]> 250 Accepted RSET 250 Reset OK QUIT 221 relay-1.mail.demon.net closing connection [Connection closed -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fyodorov, Andrey Sent: 11 December 2003 18:47 To: Exchange Discussions Subject: RE: SMTP Not Reaching Exchange Server Start doing various Telnet tests on port 25 (from outside to your firewall, from firewall to the Exchange server). You can go to http://www.network-tools.com and from there you could do a variety of tests too. For example, you could stick your e-mail address there, then select E-mail Validation, then click Submit --- you will actually see the conversation between their mail server and your mail server (or your firewall). -----Original Message----- From: Niki Blowfield [mailto:[EMAIL PROTECTED] Sent: Thursday, December 11, 2003 1:27 PM To: Exchange Discussions Subject: RE: SMTP Not Reaching Exchange Server They don't show errors, just blocked websites and such, they arent very detailed -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David, Andy Sent: 11 December 2003 16:08 To: Exchange Discussions Subject: RE: SMTP Not Reaching Exchange Server What do the firewall logs show? -----Original Message----- From: Niki Blowfield [mailto:[EMAIL PROTECTED] Sent: Thursday, December 11, 2003 8:47 AM To: Exchange Discussions Subject: SMTP Not Reaching Exchange Server Hi, Running MS Exchange Server 5.5 SP4 on Windows NT4 Single server environment, server sits on private address behind Sonicwall ProVX firewall Firewall forwards all SMTP to this server which has the IMC, has worked fine for a number of years Mail has stopped reaching mailboxes, and doesnt appear to be reaching the Exchange Server at all I would ordinarily suspect the firewall, but you can telnet to our mailserver successfully and send an email from there Our MX record points to mailgate.partition.co.uk which resolves to our Sonicwall ProVX Any ideas? I dont know a great deal about the Sonicwall I guess i could move the NT server temporarily to outside the firewall and give it the address of mailgate.partition.co.uk to see if i can eliminate the firewall Thanks Nik _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&; lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&; lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&; lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
