Hello,

I have a server with 4 IPs.

I want kerio to use IP 3 for outgoing mails but it always use IP 1. Where could I setup a binding for kerio to use a specific IP for outgoing mails (incoming is no problem as I found in a earlier post).

Thanks

Stefan

Are all four of these IP's on the same VLAN? What OS are you running?

This sounds like an OS routing / configuration issue, not a Kerio problem.

Hello,

it is a Windows 2003 server which has 4 IPs assigned (for example):

1.2.3.4
2.3.4.5
3.4.5.6
4.5.6.7

1.2.3.4 is the IP which is the primary IP of the server entered in the network-properties, the other IPs are additional IPs.

Kerio uses always the primary IP 1.2.3.4 for send out e-mails. For incoming e-mails I could bind a kerio-domain to a specific IP like 2.3.4.5 but I want kerio to use this I for sending out e-mails too.

Kerio use the IP address assigned by the operating system. When the SMTP service is listening on all IP addresses, first IP is used by OS. To use only specific IP address, configure SMTP to listen only to this IP address. Note, that this setting is valid for whole SMTP server and all domains. It is not possible to tell what IP address should be used when sending email from particular email domain defined in KMS.

Has this behavior recently been added? This issue has come up numerous times before, and there has never been a way to get KMS to use a specific IP address for sending.

I have the same issue. I have a Kerio install on a server with 10 IP's attached to it. Kerio is manually bound to 2 of them for receiving mail - that works fine. However, Kerio always sends mail out through the lowest IP number on the server and this is not one of the ones assigned to Kerio. The particular IP it uses is assigned to an Apache server. So, when larger ISP's do reverse lookups on where the mail came from that I send, they find an IP that is not running a mail server and I am finding I am getting rejected or put into SPAM folders.

I need to force Kerio to send outgoing mail through a specific IP that properly reverses to Kerio but I can't see where to set this. This is a feature that exists on every other mail server I have run ("use xxx.xxx.xxx.xxx as outgoing SMTP")

How can this be accomplished??

-----------
Server installation:
Kerio Connect 7.1
OS X Server 10.5.8
Apple G4 X Serve

I have the same/similar issue. I need to be able to specify a unique IP address to be used when sending email for specific domains.

It would be nice if the Domain > Advance > Bind this domain to specific IP address would have this effect, but as stated in a post above, this option does not bind for outgoing mail.

Unique source or destination IP? You can definitely change destination IP's by domain within Kerio.

That is great news mdhmi. Would you mind outlining how/where I can configure the outgoing mail IP per domain? I've read the documentation and gone through every configuration option I could find and see no place to do this.

Even a Kerio staff member says that it is only possible to change the IP address for incoming connections for the whole server (and not for single domains).

So mdhmi, how would you define IP addresse per domain?

You can bind a domain to an IP address for incoming connections on the domain advanced tab. I believe the only benefit is that users don't have to specify the domain when they log into webmail. Server host name and SSL certificates are global, so binding the incoming IP has very limited practical uses, as SSL will be broken on all but the primary domain.
