HI all,

My ISP sends my mail through smtp. When there is no connection with my router the mail stays at the external server. Now I want to add a second DSL connection with a different WAN Ip adres but my ISP has problem with sending the mail when it is stuck (because my first connection is down) to the other Wan IPaddress. Should it be possible for my ISP to send the mail to the second IP address.
Is setting up POP3 boxes the quickest solution to read webmail through my second DSL.

Thanks in advance

If you have a second WAN IP, setup a second MX record with a higher weight or priority which indicates which server should be used first. The lowest number is tried first. This is usually incremented in units 10. So for your main server you would use an MX entry of 10, for the second 20, etc.

Create an A record mail2.yourdomain.com -> new WAn ip
then an MX record for  mail2.yourdomain.com priority of 20 (since it's the second)

That way, if your first ISP is down, then it'll try the second mail server.

At this moment when I do an nslookup with the setq=mx option for my domain abc.com I see the following.
abc.com mx preference = 10 mail exchanger = relay1.xxx.com
abc.com mx preference = 20 mail exchanger = relay2.xxx.com
relay1.xxx.com internet addresses 111.222.333.40
relay2.xx.com internet address 111.222.333.41
Where does my ISP bring in my wan IPaddress and is it possible for him to add my second Wan ipaddress?

thank you for the given answer maybe you can explain me a bit more what the isp has to do when he owns the smtp maildelivery (I only open port 25 to my exchange server)

Now that you have the second MX setup for the domain (assuming you're using a third party DNS host) if it can't send to MX address 1, it'll send to MX address 2.

 Now that you have 2 ISPs internally, you'll need to add multiple IP addresses to your firewall or gateway so it listens on both ISPs (one for failover) Instagate makes such a hardware appliance. So when one Connection goes down, the other kicks in, and still port forwards to the appropriate server.
