Hello fellow Directadmin users,

anybody here around who is willing to use Postfix and Horde (or perhaps already doing so) ?

Would anybody else be interested in this kind of setup ?

Best regards

If you were to build postfix for a DA mailserver you'd have to fully understand the DA mail structure and change Postfix to follow it, because DA is a compiled closed-source C++ program, and you can't change how it manages email accounts, files, etc.

Horde? Now that's a great idea, albeit one that has been discussed previously in these forums.

Hello Jeff,

So you are saying:

1) DA has its own mail structure

2) Postfix doesnt understand that structure by default ?
Are you talking about the mailbox/maildir structure or issues with configuration files, aliases, formats etc ?

---

3) Perhaps I missunderstand, but there is no MTA within DA itself. Exim (or whatever you use) comes with the OS (at least on my box).

4) Thanks for the horde hint. I missed that. Lets continue the horde discussion at http://www.directadmin.com/forum/showthread.php?s=&postid=85306#post85306

Now about Postfix, did I miss something ?

Best regards

All of the above. Postfix is designed to be sendmail compatible. Exim has it's own structure, and allows almost any structure as long as it's carefully defined in the exim.conf file.

DirectAdmin uses its own structure, including support for both linux users and totally virtual users. The original exim.conf file that DA staff wrote was designed to work with that structure, and when I rewrote exim.conf for DA I followed the structure because it was already there.

It may or may not be possible to configure Postfix to use the structure. I have no idea.

What OS distribution are you using? The DA installation starts by deleting sendmail and then by building exim from its own packages.

That said, any exim build should do as long as you use a current release of the DA exim.conf file.

OS

Hello Jeff,

1) I am running FreeBSD 6.1 and on a developer machine 6.2-beta2.

2) Seems like I have to get a good grisp of that mail structure first.

On the other hand, assuming we would be able to make that transfer to a sendmail compatible format than also Postfix and other MTAs would most probably work.

3) Do you know by any chance, what was the original reason to make a different mail structure design ?



Best regards

Different from what? There's never been a standard for virtual domain email.

Sendmail is the worst; unless it's been recently changed it requires that you have a separate system user for each email address, and aliases.

Plesk's implementation of virtual domain email in qmail is interesting, but it uses qmail, which means I don't use it.

Does Postfix have it's own standard?

Postfix is using sendmails mail folder structure as far as I understand it.
 
My understanding is the same, but it's been a long time since I've looked at postfix, and I'm not sure if that's the default or if there's something else.

In any event, it's not going to look anything like DA's and it's going to be beteween hard and impossible to make it work with DA's structure.
