Together with almost everything which seems to be building within this subject matter, all your opinions are rather stimulating. Nonetheless, I appologize, but I can not subscribe to your entire plan, all be it stimulating none the less. It looks to us that your opinions are generally not entirely validated and in fact you are generally yourself not really totally certain of your point. In any case I did appreciate reading through it.

hi,

I was facing one problem which is having quiet similar messaging solution.

We are having our mail server in redundancy mode were as in redhat cluster suite in active passive mode. Openldap server is acting as a backend for storing user information.

Since more than 5000 users are there we are planning to distribute the mail service load by keeping two mailbox server and one smtp server.

our smtp server will be integrated with openldap for authentication and whenever the users logs in , our smtp server needs to verify LDAP server and query the mailhost attribute for the respective mailbox server.

Will the above mentioned solution will work or not? What is the purpose of mailhost attribute in openldap. Will it was used for the same purpose which i was mention?

Keep on going and the chances are you will stumble on something, perhaps when you are least expecting it. I have never heard of anyone stumbling on something sitting down.

Hello there! First of all, very good article.
I found it searching for a solution for my problem.

Do you use cyrus as your mail backend store?

And what about virtual domains? Several of them!

I have a similiar setup, but since I’m setting the cyrus virtdomains to on or userid and unixhierarchysep to yes, this has gave me a major problem since, now, I cannot route mail like i used to. Ie, previously we did it just like you do, username_domain_tld@backend, now with the new cyrus setup, the mailbox is not called username_domain_tld anymore, it’s now called as username@domain.tld; We added the domains cuz there might be 2 mailboxes with the same name but in diferent mailboxes, for example, the postmaster@domain1 and postmaster@domain2

This brings an RFC problem username@domain.tld@backend, ie, the 2 @’s. Now we can’t get the mail to be routed. If our mailRoutingAddress is set to username@domain.tld@backend, the alias won’t even be found.

You seem to have enough experience, at least to point me into some direction.

Please!
