1 email provider but two ISPs.
Hi all, I have two ISPs access Kenya and JTL both providing Internet but access Kenya provides Email services too. At the office there is a server which fetches the emails from the the Email server at Access Kenya and users use mail clients to access the mails. I would like to add the JTL link as failover to still fetch mails when the Access Kenya's internet link is off. -- Regards, Job Njogu Muriuki, Phone: (+254) - 722906324 | 736333075 Skype: heviejob | Yahoo: heviejob Address: 42665 00100 Nrb
So what is your question? :) Also hard to advise if you don't share some information about the kind of hardware you have terminated your internet links into... Best regards, Mblayo On Mon, Feb 11, 2013 at 1:52 PM, Job Muriuki <muriukin@gmail.com> wrote:

Hi Job, I don't think your server "fetches" mail from Access Kenya since they don't give POP3 services, but rather mail is delivered to your server by MX, AKs server just being your primary MX with a static route to deliver to yours. That's an assumption, because you did not give any details on your domain name. If the foregoing is true, then your server will NOT be able to get any e-mails from AK when AK link is down. Why? Because the static mail routing configuration at AK does NOT include details of your IP from JTL - unless you publish that in DNS and unless AK includes it. I know AK does not deliver by MX purely - they use static routes on their MTA, but you can ask them to change this. Also, I have this feeling that your outbound mail traffic is on the AK link. If that is so, then complications arise when you start sending out mails via JTL link, unless you publish your mail server's A RR records to include both IPs. If you use a smart host to relay, it becomes even thicker. However this was not in your question:) On 11 February 2013 13:52, Job Muriuki <muriukin@gmail.com> wrote:

hi, The best solution if to have your own set of public IP's so that you can assign it to the mail server. Also with your own ips you can do BGP with both AK and JTL so that no matter which provider you are using the mails can still reach the server. You can organize a meeting with both AK and JTL so that they can design for you the product.. -- *Regards, Amos k Sang | Technical Consultant* On Mon, Feb 11, 2013 at 1:52 PM, Job Muriuki <muriukin@gmail.com> wrote:

Hi Amos, Usually providers won't announce any prefix longer than a /24, which would be an overkill to assign simply because a mail server exists on the network. Job, you still haven't described your setup in enough detail. Do you use POP3 to fetch the emails from a catch-all mailbox, or is the email delivered via SMTP to your server? Regards, Steve

The solution is doable with no BGP or any other dynamic routing protocol. BGP is a looooong shot in such a case.
Think they are relaying to you through 'MTA transport' or forwarding via local DNS names. -> ASK YOUR DOMAIN registrar to point MX to your router IP with right priorities, eg provider A with priority/pref 5, and provider B with pref/priority of 10 or above. -> Configure IP Sla if Cisco router. If firewall like cyberoam they have the option as well. -> Do dNAT and point both static NAT entries to the email server. option 2 -> Ask your provider to host your mails - "catch all" and POP there - a retrogressive move though.

@ Amos & Job: For that to happen, any interested party will have to apply to AfriNIC for a block of public IPs & a public AS number...
All that trouble for a single mail server?
@ Steve: I'll politely disagree with you there... I've configured B.G.P. transits where /20s & /21s are being received from ISPs who want their IPs to transit over a partner's network... (Tricky stuff though!)
Moot point.....what's longer, a /24 or a /21? What you've described is fairly routine but I'm yet to see any provider who'll announce anything longer than /24.
Anyway, Job still needs to answer some fundamental questions regarding his setup, before we can chime in with workable solutions. Like Brian mentioned before.

I suspect AK's MTAs have smtp routes to the server's public IP. IIRC they can set up multiple SMTP routes to the customer and they'll be treated in a round-robin fashion (at least smart MTAs should do this). So with 2 static NATs set up on the router (one for each public IP) this would be a breeze. Assuming failover between the two links is automagically handled by the router then outgoing mail should work OK as well with a caveat; if he's relaying out through AK they need to allow outbound relaying from his JTL IP. Still not enough details though to complete the picture... Regards, Steve

My point exactly, you have it inverse. The longer the prefix, the more specific the route.
/24 is *longer* than /21 - check the wild cards and subnetting concept :) Usually most ISP wont accept longer than that. /24 is 11111111.11111111.11111111.00000000 /21 is 11111111.11111111.11111000.00000000 Wilson./

Usually most ISP wont accept longer than that. No ISP I know of will accept that, which returns us to - why use a /24 for a single mail server?

Job, AK deliver mails statically via IP. In your scenario, I'd propose a round robin whereby we shall create an A record resolving to both AKG and JTL IP addresses. In the event the AKG link goes down the server will be reachable on the JTL IP and mail flow will not be interrupted. You may not that outbound will be interrupted if you use AKG smarthost as it does not allow relay / not open for relay. To be able to deliver you may opt to relay via DNS of either ISP. You may contact our support on 3600200 for more. Kihanya AKG On Mon, Feb 11, 2013 at 1:52 PM, Job Muriuki <muriukin@gmail.com> wrote:
Hi all,
I have two ISPs access Kenya and JTL both providing Internet but access Kenya provides Email services too. At the office there is a server which fetches the emails from the the Email server at Access Kenya and users use mail clients to access the mails. I would like to add the JTL link as failover to still fetch mails when the Access Kenya's internet link is off.

With that type of connection, it doesn't even make sense to relay. Just send out straight into the wild - as long as you publish the right DNS records for the IPs - and you can go further and include SPF.

Wouldn't a better solution to OPs problem be to setup an MX record with lower preference pointing to JTL? He only wants to use JTL as a backup link.
