Hello,

I'm wondering if it's possible to disable local delivery for the 'mail domain' the KMS is configured for when using a relay smtp server for outgoing mail.

This is the last step in getting KMS to work in a way we need it to. If it's not clear, i want ALL email to go through the relay SMTP host i configure under "SMTP Server -> SMTP Delivery", also email with a recipient that's within the domain KMS is serving.

It doesn't work that way. Mail addressed to the local domain doesn't get processed by the SMTP components of the server, it gets delivered right to the user mail store. Even if it did, SMTP relay servers are only used for remote delivery.

The best you could do is use the archiving feature. Set up a remote address to archive to. That will get everything.

This is not possible.

Why would you want local mail to make a detour through your relay server? I see no reason for that.

Thanks for the answer and explanation.

The scenario in which this is important is that we have a present mail cluster, processing all our <_a.t_>company.com email.

We intend on using KMS purely for it's shared calendar function. During some tests with a KMS host using employee<_a.t_>subdomain.company.com this ended up in people receiving calendar event invitations from that sender.

However when accepting the invitation in iCal for example, it would get accepted as employee<_a.t_>company.com. Creating duplicates for every invitee and acceptee, ie. both employee<_a.t_>company.com and employee<_a.t_>subdomain.company.com would show up in the list of attendees.

My planned dirty work around was to have a KMS act as a <_a.t_>company.com server and simply relay all the email though our regular SMTP servers, so people would receive calendar invites as employee<_a.t_>company.com and could accept them as such.

So you have a mail cluster (not KMS) that handles SMTP, POP3, IMAP and maybe other stuff, but not calendaring. For calendaring you plan to use a KMS server. Have I understood this right?

That means, you would have to create each user on the mail cluster AND on KMS. And delete them, when they leave the company.

Isn't that an administrative nightmare? Why not use a mail solution that handles mails and calendars?

AFAIK, KMS only relays mails if:

- the domain of the recipient is not existing on KMS
- the recipient is not existing on a local domain (has to be configured through domain properties)

So it is probably not possible to achieve what you want with KMS.

The administrative nightmare was the least of my worries, but also not an issue once i got KMS to work with LDAP.

We're just receiving a high amount of pressure from the management regarding a shared calendar solution and this seemed to be ideal, aside from the minor glitch with duplicate attendees on meetings.

I really like KMS and really want to use it for just this. My next attempt would be to have the KMS operate under <_a.t_>subdomain.company.com and have it relay all email through our mail cluster that rewrites the from header to <_a.t_>company.com.

Though that's far more complicated then I was hoping it would need to get. :-/

It sounds likely to me that more people have different email and shared calendar solutions. Any suggestions would be more then welcome.

What do you mean by "have it relay all e-mail through our mail cluster"? I still don't have the full picture here. Questions:

- The Mail client is communicating with the mail cluster through SMTP/IMAP. KMS is NOT used for communicating with the Mail client (e.g. Thunderbird). Is that correct?

- Is Calendaring handled through the same client? Or does the user need a separate application for calendar?

- When the Calender Application accesses KMS, does it do that through ical?

- How is the mail flow exactly? Internal Mail: Cluster -> Kerio -> Cluster. External mail incloming: Internet -> Kerio -> Cluster. External Mail outgoing: Cluster -> Kerio -> Internet. Is that correct?

- Are you expecting that KMS filters the meeting requests and puts them in the calender and just lets pass all the other mails unaltered?

To propose a solution, I would really need any info you have.

Correct.

Correct, we use Mail.app/Entourage or Thunderbird for mail. And iCall for calendar.

The mail isn't supposed to flow through Kerio at all. Only when people create a meeting through the webinterface, it sends out an email through Kerio to the invitees.

And this is where the problems occurs. In my test setup I have Kerio running on subdomain.company.com, resulting in people receiving their meeting invites from user<_a.t_>subdomain.company.com. However, iCall accepts them as the configured mail user on your system, so they accepted as user<_a.t_>company.com.

I created accounts for a few test employees on Kerio being, employee<_a.t_>subdomain.company.com. Instead of being actual mail accounts, I simply had all their email forwarded to their real email accounts being employee<_a.t_>domain.com.

Resulting in every meeting having an unaccepted invitation for user<_a.t_>subdomain.company.com and an accepted invitation from a non-invited user being user<_a.t_>domain.com (for some reason this is allowed).

Like i said, i don't want KMS to touch *ANY* email whatsoever. I just want to use it for the shared calendar functionality. We already have an email solution, that processes all the companys ingoing and outgoing email.

KMS should solely act as a calendar service, however it's unusable unless it can send out meeting invitations as user<_a.t_>company.com.

Imagine inviting a 100 people to a meeting and getting a list of 200 due to duplicates.

I hope i answered all your questions. If something is still unclear, please ask.

Ahh, now I understand. What I would do is setup the subdomain calendar.company.com. All the users on KMS would then have an adress like user<_a.t_>calendar.company.com (I think you have done this already).

You would then need to configure every user on KMS to bounce every mail to user<_a.t_>company.com. (User properties > Forwarding tab).

When someone want to send out an appointment, he needs to address it to user<_a.t_>calendar.company.com. This then gets automatically forwarded to your mail cluster. If someone accepts the meeting this generates a mail to user<_a.t_>calendar.company.com. KMS will the automatically record the acceptance as user<_a.t_>company.com (which is what you want).

That's what I had figured out aswell. Though the problem arises when someone creates a meeting through iCall and then invites employee<_a.t_>company.com.

The message doesn't pass Kerio and the event isn't registered on the public calendar.


Inviting employee<_a.t_>subdomain.company.com works fine, but then the duplicate invitee problem is back.
