:) ok thanks for the help Our DNS is provided by our ISP, I guess I need to ring them and find out whats going on, we changed about a week ago and instructed they change our MX, I assume it should be fine by now?
When I test it from here I get the new IP, so some servers are aware (and this is my home connection, which is on a different ISP to the corporate, so different DNS servers) Thanks again -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Martin Blackstone Sent: 11 December 2003 21:38 To: Exchange Discussions Subject: RE: SMTP mail not reaching Exchange Server Roh roh -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ely, Don Sent: Thursday, December 11, 2003 1:28 PM To: Exchange Discussions Subject: RE: SMTP mail not reaching Exchange Server I see 62.49.146.170... www.network-tools.com sees: IP address: 62.49.146.170 Host name: mailgate.partition.co.uk Alias: no-dns-yet.demon.co.uk Your DNS is outta whack -----Original Message----- From: Niki Blowfield [mailto:[EMAIL PROTECTED] Sent: Thursday, December 11, 2003 2:56 PM To: Exchange Discussions Subject: RE: SMTP mail not reaching Exchange Server Hi Don What address do you see as my MX?

In the Sonicwall, under the advanced setting, you should have it setup under one-to-one NAT the public/private translation for your Exchange server. Then under Access have a rule to allow port 25 to that private address. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Niki Blowfield Sent: Thursday, December 11, 2003 2:48 AM To: Exchange Discussions Subject: SMTP mail 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] _________________________________________________________________ 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]
