Anything but MS is my motto, for different reasons that aren't important right now.

But before I switch, or try and convince the large company I work for to switch I need at least 2 answers:

1: How many accounts can the server manage? Is there a max?, and has any location come close to that max.

2: Once thing that I hate more than anything about the ms exchange diservice (please say no) is that one can only have on email account active at a time. It is so inhibiting.

With the simple apple xserve mail server I can monitor my account, my bosses account when she is out, my associates and customer service all at the same time. It is so practical and so impossible with the MS diserver.

1) I do not know. Please specify "large company"
2) You must see three situations:
a) Webmail: Only one account can be viewed at one time
b) Netscape: View as many as you want
c) POP3 Retriever: you can select for each retriever a incomming internal account. It is in your requirement how much you place to one internal account.

If you create some internal accounts for an user like
It is not a problem to create up to your maximum licenced users for only one person.
It is only a matter of the Webmail that you can see only one account at one time. But when you are using Netscape or Thunderbird you are free. At some point you will loose the overview of all active accounts for a specific user.
The limitation is not with the number of users added or created, but the number of concurrent connections. The Kerio MailServer currently is still undergoing development for a clustered model, so in the meantime, the number of concurrent connections is limited by the hardware in a single server model.

Each organization can have very different email usage. Two companies with the same amount of users will have different hardware, networking, and mail server feature requirements that may or may not be supported.

So it has to be determined on a case by case basis. You can always contact Kerio to discuss your mail server needs to determine if the Kerio Mailserver is for you. Just fill out the form at and someone will contact you. Or contact sales at: 408-496-4500 (US) sales<_at_>

I have understand the question more in the way of asking how much users can be created until the server hangs on searching and managing the created useraccounts as on working for connecting these users via POP3, IMAP, SMTP, WEBMAIL.

That the trafficload is different from company to company is normal and can not be answerded without load and usage logs.

But to know how much users can be handeled when someone purchase a unlimited licence is also a interesting point to know. I think there would be a difference for managing the entries for 1,000 users and 100 Domains as for 1,000 and 150,000 users. Not about managing the traffic, just and simple about managing the useraccounts on the setting file and time to connect a user which is the last in the setting file. When a software has an unlimited licence I like to see it word by word with the right hardware...

Does someone has still created a huge amount of users and domains or does Kerio has some information about they are interested to share here???

Ask to the mods: A sticky threat for "lagest installations ever" for sharing such information?
