Hi Folks,

here's my problem:

I am running a mail server hosting several domains. Each domain has it's
"own" mail server. E.g. imap.domain1.com imap.domain2.com.

Now it is always the same server answering the call. In order to log in, my
users need to use a login name as user@domain1.com for Cyrus to know who is
it. But I wish they could log in as "user" without the @domain1.com part.

Is there any way for Cyrus to find the domain part in the imap.domain1.com
part?

Another problem is that I wish to block some users from logging in if they
are not in "my" network. E.g. If you dial in with me you are free to check
your mail, but if not you are not. On the other hand if you pay extra, you
are welcome to check your mail from whereever you are. Oh, don't worry. I do
this for a hobby. Not realy earning money in this way. ;-)

Thanx a lot.

No. Neither is there a way to do this with any IMAP server. This is not
possible due to some technical IMAP aspects.

The closest possible thing is to assign a different IP address to each
hostname; some IMAP servers -- I do not know if this is possible with Cyrus
-- may be able to differentiate and supply the default domain based on the
IP address the client connected to.

I do not believe that this is possible with Cyrus.

Cyrus can do such a behaviour.
Default Cyrus' virtual domain support is IP adress base.
virtualdomain: on
You can select user id base.
virtualdomain: userid

Cyrus can do IP address based access control with tcp_wrapper.

Sorry, i am a little unclear about this.

In my understanding, if i use virtualdomain: userid, then i have to use
username@domainname to login to the server except the default domain.
Would you mind explain more about the virtualdomain things more
clearly to us?

Thanks very much.

If you use virtualdomain: on, then
If your server have two IP addresses,
192.168.1.1 mail.example.com
192.168.1.2 mail.example.net
and client connect to 192.168.1.1,
then login user `foo' is treated as `foo@example.com'.
connect to 192.168.1.2, as `foo@example.net'.
