SMTP routing iMS 5.2

A simple question, how can I specify the MX ip address of a particular destination domain ( bypassing dns MX lookup )
Ims version 5.2P1 Ids 5.1.
This setting was possible in NMS 4.x editing local.conf file
es : service.smtp.smtp-routernsmsghostrewrites: testdomain.com:10.10.10.2
thanks

Another way in the imta.cnf you could have done
testdomain.com $U%$D@tcp_other-daemon
then create a tcp_channel for this domain
tcp_other smtp daemon 10.1.1.1 subdirs 25 ..etc.
tcp_other-daemon
and route the mail to host 10.1.1.1 that way.
But the hosted domain method probably is better
in the long run. Easier to modify ldap than
editing the imta.cnf each time.

IMS 5.2 SMTP routing

How to setup SMTP routing on iMS 5.2?
For example:
For domain1.com MX is server1.domain1.com
server1.domain1.com (iMS 5.2) have one user (email: [email protected]).
I want to server1.domain1.com route messages for other users to server2.domain1.com.
How to do this?
Peter

In order to route your mails to server2.domain1.com, you need to edit your LDAP domain entry (should be cn=domain1,cn=com,o=internet or so) and add a "mailroutingsmarthost" attribute pointing to server2.domain1.com.
then imsimta refresh
That's it.
Good Luck

Notes :
If your server is working in Direct LDAP mode,
apply patch 1 before adding the attribute.
If server2 is an old version, I suggest you add the "dequeue_removeroute" keyword in your tcp_local and tcp_intranet channels definitions (imta.cnf file) or you'll get rewriting errors from the old server.

SMTP routing table does not seem to be working correctly.

Why isn't the SMTP routing table working properly?

First, make sure you have the routing table setup correctly.
Entries in the Routing table are in the following format:

<incoming recipient domain>:<route to this host>

For example, if you want all mail addressed to [email protected]
to be routed to mailhost1.realdomain.com, you would add the following
line to the SMTP routing table:

virtualdomain.com:mailhost1.realdomain.com

With the above option, any mail coming in addressed to <anyone>@virtualdomain.com
will be routed to mailhost1.realdomain.com. The recipient email
address will not be re-written, so mailhost1.realdomain.com needs to
accept mail addressed to the original address, @virtualdomain.com,
even though it is in realdomain.com.

Before adding, changing or deleting any SMTP routing table entries, double-check
with the DNS Administrator that the host names you specify are valid,
registered host names. If in doubt, you can use IP addresses for the
"route to" host, but not for the "incoming recipient domain".

Wild cards can be used in mail routing table options, but they indicate that a
hostname will fill that spot. For example:

*.domain.com:mailserver1.domain.com

In the above example, any mail addressed to <anyone>@<anyhost>.domain.com
will be routed to mailserver1.domain.com. However, mail addressed to
<anyone>@domain.com will not be routed. To fix this, add this
line:

domain.com:mailserver1.domain.com

Note: You cannot use the SMTP routing table to route all mail
addressed to a specific domain to a specific account. You would need to use
a "Mail Pool" account for this, which is only available in Messaging Server
3.5+.

SMTP route priority

Hi,
I've a general question about SMTP routes. Suppose, that I've 3 SMTP routes
- Domain foo.bar, configured via Network->SMTP routes
- Domain *.foo.bar, configured via Network->SMTP routes
- Domain foo.bar, configured via LDAP routing query
Which one has the highest priority?
Thanks,
Axel

LDAP routing has priority over static SMTP routes except in the instance where you have defined the ALL: route which then overrides LDAP.

TLS mutual authentication and Separate default SMTP routes per listener - IronPort c370

Dear all ,
We have two IronPort C370 ESAs , formed in a cluster.
We are in a need to route e-mails targeted to a special group using TLS Required/Verify.
I have two questions :
1. Is TLS mutual authentication possible on both incoming and outgoing ?
2. Due to the nature of the TLS need the existing listener cannot be used. So I created a new listener and respective filters to decide when the recipient requirements are met. The new listener is going to be configured with a policy specifying TLS required/verify. Problem is that there is always a default SMTP route pointing specifically to a cloud service rather than directly to the Internet while for the new listener usedns is required. Is it possible to have two different default SMTP routes assigned to different listeners ?
Thanks and kind regards ,
Gino.
PS : Please bear with me and questions. I am making my first steps in Iron Port administration.

I have made some sort of progress but I would also like to have your expert opinions.
I have came to understand that in order to present TLS mutual authentication for the incoming traffic I will just have to trust the sender(s) CA ( containing SANs etc for both the SMTP domain and the ESA itself ) while if I spread own SANs to the counterparts I will also have TLS mutual authentication on the outgoing traffic as well. Issue is that I will have to declare it in destination controls and it cannot be generic.
Is there any way to make TLS required/verify with mutual authentication the default without having to set destination contol(s) ?
As for my second question I have came to understand that the additional listener is not an aditional MTA and concequently I cannot have separate default SMTP route ( default = what is called as "ALL" in IronPort ). Still if anyone knows something more it would be really helpful if it was shared.

Alt-Mailhost / SMTP Routes Question...

Hi All,
I have a query on SMTP routing when using the Alt-Mailhost command in a Message Filter...
Our configuration in overview is two Ironport devices (C650's at AsyncOS 6.4) at separate sites, configured as a cluster (all config is common across sites). At each site, there also exists a 3rd party mail host.
So, I have a message filter which selects messages based on some criteria and I also know which Ironport received it. When I have a match, I want to route this message to the 3rd party mail host on the _local_ site......but if that mail host is down, I want to route it to the 3rd party mail host on the other site. Simple as that!
At the moment, my Alt-Mailhost command looks like this;
<message has been selected> {
<if "Site A" Ironport used> {
alt-mailhost('bogusdomain1.net');
<else>{
alt-mailhost('bogusdomain2.net');
...in my SMTP Routes I'd _like_ to have this;
bogusdomain1.net <3rd-Party-Box-at-Site-A>, <3rd-Party-Box-at-Site-B>
bogusdomain2.net <3rd-Party-Box-at-Site-B>, <3rd-Party-Box-at-Site-A>
...but this doesn't work because multiple hosts in an SMTP route are tried in numerical / alphabetical order...no matter what order you put them into the SMTP Route definition (is this a bug?)....so in reality, they both have to look like this;
bogusdomain1.net <3rd-Party-Box-at-Site-A>, <3rd-Party-Box-at-Site-B>
bogusdomain2.net <3rd-Party-Box-at-Site-A>, <3rd-Party-Box-at-Site-B>
..which is no use.
My only other idea is that I could just have this in the SMTP Routes for those domains;
bogusdomain1.net USEDNS
bogusdomain2.net USEDNS
...and configure my DNS with the above domains, such that there really _is_ a difference in the order of the MX for those domains.
So my question is, how can I do this without using 'USEDNS' and the associated DNS config...i.e. just via the Ironport devices?
Hope the collective can help!
Cheers, Chris.

Ironport back-up smtp routes

Hi Guys,
I have 2 lotus notes servers. Is it possible on the ESA to add these two servers on the SMTP routes while using the same domain name?
How will the ESA forward incoming mail then? Some sort of load balancing, or will it be a priority thing?
Thanks,
Adrian

Hi Adrian,
Q:
I have 2 lotus notes servers. Is it possible on the ESA to add these two servers on the SMTP routes while using the same domain name?
A:
Yes. Please use SMTP Routes option, under Network > SMTP Routes.
Q:
How will the ESA forward incoming mail then? Some sort of load balancing, or will it be a priority thing?
A:Whenever the appliance accept the connection and the message from the sender host, it will check the destination domain of the recipients and look up for SMTP route to reach that destination domain. If there is a SMTP route the appliance will then use the information configured on how to reach the destination. If you have version 7.x of the AsynOS which allows priorization, then the appliance will follow the configuration. If both destiantion servers configured have the same priority, round-robin fashion will be applied.
If you are running a version prior of AsyncOS 7.x then the appliance will connect to the first server configured. If that server is unreachable then it will try the next one configured.
SMTP Routes Overview
SMTP Routes allow you to redirect all email for a particular domain to a different mail exchange (MX) host. For example, you could make a mapping from example.com to groupware.example.com. This mapping causes any email with @example.com in the Envelope Recipient address to go instead to groupware.example.com. The system performs an “MX” lookup on groupware.example.com, and then performs an “A” lookup on the host, just like a normal email delivery. This alternate MX host does not need to be listed in DNS MX records and it does not even need to be a member of the domain whose email is being redirected. The Cisco IronPort AsyncOS operating system allows up to forty thousand (40,000) SMTP Route mappings to be configured for your Cisco IronPort appliance. (See SMTP Routes Limits.)
This feature also allows host “globbing.” If you specify a partial domain, such as .example.com, then any domain ending in example.com matches the entry. For instance, [email protected] and [email protected] both match the mapping.
If a host is not found in the SMTP Routes table, an MX lookup is performed using DNS. The result is not re-checked against the SMTP Routes table. If the DNS MX entry for foo.domain is bar.domain, any email sent to foo.domain is delivered to the host bar.domain. If you create a mapping for bar.domain to some other host, email addressed to foo.domain is not affected.
In other words, recursive entries are not followed. If there is an entry for a.domain to redirect to b.domain, and a subsequent entry to redirect email for b.domain to a.domain, a mail loop will not be created. In this case, email addressed to a.domain will be delivered to the MX host specified by b.domain, and conversely email addressed to b.domain will be delivered to the MX host specified by a.domain.
"The SMTP Routes table is read from the top down for every email delivery. The most specific entry that matches a mapping wins. For example, if there are mappings for both host1.example.com and .example.com in the SMTP Routes table, the entry for host1.example.com will be used because it is the more specific entry — even if it appears after the less specific .example.com entry. Otherwise, the system performs a regular MX lookup on the domain of the Envelope Recipient."
From our documentation:
"A receiving domain can have multiple destination hosts, each assigned a priority number, much like an MX record. The destination host with the lowest number identifies as the primary destination host for the receiving domain. Other destination hosts listed will be used as backup.
Destinations with identical priority will be used in a “round-robin” fashion. The round-robin process is based on SMTP connections, and is not necessarily message-based. Also, if one or more of the destination hosts are not responding, messages will be delivered to one of the reachable hosts. If all the configured destination hosts are not responding, mail is queued for the receiving domain and delivery to the destination hosts is attempted later. (It does not fail over to using MX records)."
I hope this helps.
Cheers,
Valter

SMTP Routes, DNS and Failover

Hi !
I'm configuring an outgoing server (i.e. only a private listener) on ESA C370 with AsyncOS 8.0.1.
I use the Internet's Root DNS Servers, and my default SMTP route is empty. My ESA is connected to 3 networks : production (default gateway), administration and failover (1 interface/network).
I would like to deploy a failover solution with an extra ESA on the failover network : if I lose my internet connection (impossible to join DNS and remote MX), my ESA would redirect all its mails to the extra ESA.
How can I do that ?
Thank you for your help.
Best Regards
Quentin

The ESA has no way to automatically fallback to a static IP if DNS in unreachable. The best on-box solution I can suggest is manually changing the 'All Other Domains' SMTP Routes entry when such an event occurs.
I hope this helps!

Ironport Management appliance and smtp routes

Hi Guys,
I'm configuring M170 management appliance for two mail security Ironports (for centralized quarantine).
while going through the configuration, i have found that there is SMTP route can be configured, why do i need to configure SMTP route under the management appliance?
As i know it should be confgured on the Ironport email security appliances, but why on management? Do i need it?
Thanks & Regards,
Rami

Hi,
Thanks for your reply, just want to confirm, this is will be used even for end users Quarantine notification, correct?
I mean that Management appliance will send quarantine notifications to end users by using this smtp route, am i right?

Perl-script Net::SMTP and iMS. How To? :(

How to configure iMS to send mail with Perl-script using Net::SMTP module?
Script and iMS must run in different hosts.

Thats more a topic for perl and smtp than it is for IMS. Anyway, you could do:
unshift @{$Mail::Sendmail::mailcfg{'smtp'}} , 'mailserver.host.com';
%mail = (
To => '[email protected]',
From => '[email protected]',
Message => 'this is my message!,
Subject => 'Test Subject',
sendmail(%mail) or die "Mail Not Sent!";

SMTP routing all messages to Postmaster to Root and then null...

Anyone got any idea what might be causing this...?
Have a very simple OS X Server. Until upgrading to Server 3 / 10.9 it all worked fine. Then, after upgrade, I stopped getting mail on the Postmaster account.
Digging into SMTP log shows that server is simply forwarding all mail to postmaster to the root account, and then forwarding those messages to the null device.
Here is a lightly obscured entry from the log illustrating:
Oct 29 22:00:52 www.abc.xyz postfix/local[46314]: 4D5091253EA8: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0.01, delays=0.01/0/0/0, dsn=2.0.0, status=sent (delivered to file: /dev/null)
I have no idea why it is doing this, but would very much like it to stop! Called Applecare and they didn't know anything - suggested I read the 'advanced administration manual for Server 3' - which I did. But doesn't contain anything meaningful on this topic.
Any help anyone can offer would be most appreciated!

Thanks for the info. That's stopped the messages being forwarded from root to the null device, but they are still being sent to the root account - not sure how to access these messages (as there is no obvious way to access the mail forwarded to root account: there is no 'root' account defined for the mail server).
Here is an example of the messages concerning this in the log...
Oct 30 11:33:18 www.abc.xyz postfix/pipe[36354]: 761F612672E3: to=<[email protected]>, orig_to=<[email protected]>, relay=dovecot, delay=0.04, delays=0.01/0/0/0.03, dsn=2.0.0, status=sent (delivered via dovecot service)
Thanks in advance for whatever help you can provide.

SMTP Routing in Exchange 2013

We are migrating from Exchange 2007 to Exchange 2013 and I have some questions around the mail flow changes in 2013.
I understand that the CAS role plays a part in mail flow now. We have our 2013 CAS servers installed as a separate role.
Should we direct our internal applications to the CAS servers for SMTP mail delivery or should it be the Mailbox servers?
Should the external mail flow next hop from our SPAM firewall be the CAS servers?
Where should we apply receive connector rules, CAS or Mailbox?

Hello,
For your applications, if the recipient is a internal user, you can configure internal SMTP relay via the frontend transport service. If the recipient is an external user, you can configure external SMTP relay via the frontend transport service.
The frontend transport service is on CAS server.
Here is an article for your reference.

You're right. The external mail flow next hop from your firewall will be CAS servers.
You should apply transport rule on Mailbox server.

New POP & SMTP routes down?

I have two different systems accessing my FIOS email accounts using Thunderbird 17.0.2.
On the machine I have updated server settings at Verizon's request from incoming.verizon.net and outgoing.verizon.net, to pop.verizon.net and smp.verizon.net. Also changed authentication to SSL/TLS per the instructions.
As of roughly 11:00 am EDT (Maryland), the new setting no longer function. Restoring them to the originals, or using the other system that was never upgraded gets me lightning fast incoming AND outgoing email again.
Anyone else suffering from this?

I have also made the changes updating my Thunderbird server settings as requested by Verizon. It works well when it works. The problem I am having is that it is intermittent. It will work for a while then go down for several hours. I called Verizon, the service agent said the IT group is reporting no problem which I assume means they are not bothering to test it on a regular basis. They also don't seem to care and they esentially said if I need email service to go through the web tool. The problem I have with the web tool is that it doesn't allow me to keep my sent messages in Thunderbird.

Inbound mail routing based on LDAP attribute mailsystem

Hi gents and ladies,
i have a small question ...
is it possible to route an email to a recipient based on an LDAP attribute like mailsystem or ldap attribute domain ?
We have an infrastructure with domino and Xchange. All users have a - so called - maindomain.net SMTP Address.
Is it possible to manage such routing via mail policies or message filters ?
Or is it just easy to realize this jjust with SMTP routing list ? e.g. maindomain.net gets an entry in SMTP routing pointing to the domino gateway ... if no delivery is possible the default gateway (Xchange gateway) would be used instead ?
Thanks in advance for your help and hints.

Hello HPGroh2013,
I think I answered your question in the previous entry, at least it looks the same to me.

Andreas
