Tracert assumes the wrong ip-address

We have an exchange server on sbs 2003 that used to work perfectly. We have moved to another town and now the mail does not come in anymore. Surfing and outgoing mail pose no problem. We have not changed the configuration except of course that our internet provider has given us another outbound ip-address. There seems to be the problem. IP-Config gives the new outbound ip allright, but when I do tracert to my mail server at mail.richel.org it times out.... because it uses the old outbound ip-address. I can however not find the location where to change that.

Just to be clear, your ISP has assigned you a new IP. Inbound and outbound really don't factor in here, it all uses the same IP (I won't go into certain multi-IP scenarios here). However, for inbound traffic that has initiated at an external source (like email being sent to you), it has to be directed to the correct IP for it to reach you. In this case you need to change your public DNS records to reference your new IP.

In general for email you need a MX record, an A record, and a PTR record.
The MX record points at a FQDN like "mail.richel.org".
The A record connects a FQDN like "mail.richel.org" to an IP. Since your IP has changed, this is the record you will need to update. This has to be changed wherever your DNS records are hosted.
The PTR record is somewhat optional, but many companies will block email from you if this is not configured properly. This record connects an IP to a FQDN. Typically your ISP will have to change this record. You should have one created for your IP that references "mail.richel.org".

There are some good sites out there to help you test your own server like mxtoolbox.com, dnsstuff.com, intodns.com, etc.

Well gentlemen thanks, but I am not getting anywhere.
1. I have edited the dns details at my name registrar (Hover.com) and he informs me that this is all useless since they do not run the nameservers ns1.fastdns.net | ns2.fastdns.net
2. these nameservers belong to my website host olm.net but in their control panel is no option to edit dns records
3. off course i mailed them, but I am waiting several days now for a reply

I will wait and push more, but please tell me if I do something wrong.

(The MXtoolbox.com site seems useful but I do not know how to interpret the results. A first lookup fails "after 1 name servers timed out or responded non-authoritatively' and when I then click 'Find monitors' I get a list with addresses only confirming the old - obsolte - situation. So I do not know what to do with this information.

Gentlemen, a telephone call with the ISP solved it all . Your advice was very handy though.

Thanks
