Hello,
I downloaded and used a trial version of Kerio Connect.
I have identified 5 IP addresses on the server. These are real ip addresses.
When I want to send an e-mail from the server, I want to go on one of the 5 defined IP addresses. Is this possible?
So I want all outgoing mails to go from these ip addresses at random.
Thank you.

You do know that, without proper PTR records, this behavior would look suspicious and presumably cause your outbound email to be blocked.
If you have unique domains, then you can bind a domain to a specific IP address in Configuration-Domains-Advanced.
I don't see a way to attach a domain to multiple IPs.
Cheers,
Jon

No problem for one domain to have different IP addresses or the IP address different domain names.
If the server has 5 real addresses, Kerio should listen on all of them. Sending is a different matter - this is usually set within the OS and what IP address the main gateway is.
To get it right, decide on ONE IP address for mail - it makes things WAY easier. You can add all IP addresses to the DNS name and add for every IP a reverse DNS entry to your domain.
Then as DNS MX entry use the IP you need for the mail server and that is the standard gateway. IF you really want all IP used, add MX entries for all of them, but do it with prio like 10 - 50, so one IP gets used as a primary.
You can also bind kerio to a specific, outgoing address. And that would make the most sense IMHO.
There is no advantage for using 5 IP on one server. 5 Servers with 1 IP each is a different matter, but one IP works as fine as 5.
