Those things sound like tinny steal drums wrapped around your ears!
Get some Shures!

I was just about to echo your words.

I used entourage for a short while. Thought I was going to go the whole project route in office.

I'm back with mail.app which is superior to entourage.

I have to agree. Entourage has some big limitations. The biggest is that all received mail goes into one database for all folders, and there's a limit to the size that this file can be. It used to be 2 GB, but I think it's a higher limit now.

As soon as you reach that limit, Entourage will crash, and you can't access your mail. At least now it warns you that you're getting close (though most people don't understand what the warning means). Two versions ago, there was no warning, just one message too many downloaded from the server to take you over the edge, and then nothing.

And what makes it worse is even attachments go into this single database file.

Mail solves this problem by having a separate file for each mailbox, and attachments go into a separate folder. I'm not sure on this, but I've noticed a significant performance hit (and perhaps an inaccessibility issue) if any one mailbox gets above 1.5 GB. Since I noticed this I've managed my boxes to avoid getting up to 1.5 GB, so it could have been fixed by now, and I wouldn't know it.

Another benefit to having one file for each box is that you can do rebuilds for a single box in Mail. In Entourage, you have to rebuild this huge, single database that contains all your mail, and it takes forever and locks up the whole thing while it's working.

Anyway, that's just some ways I've noticed that Entourage is inferior.

The scheduling/To Do List/Calendar features in Entourage are nice, but the next version of Mail will contain similar features, to be released in Leopard (the next update to OS X). The execution of these features looks pretty nice and a good improvement over what Entourage offers.

I'm a pretty heavy mail user, receiving about 300+ messages per day with around 100 containing attachments. In general, mail apps choke with volume this big. There are a few that will work decently. Mail is among them. It is far from perfect, but it manages to stay upright when you throw a big load at it.

Integration with iChat and Address Book is pretty nifty, too, btw. Oh- and LDAP integration works quite well. Couldn't get by without LDAP.

Guess we are going OT here....
but swise, you've convinced me to try mail.app again. I was using it for a while and then went back to Entourage...
I run my own Exchange server and keep my mail there (although both Mail and Entourage keep local copies too)...
The biggest problem I have with Mail (and Entourage has this too) is that they don't update sub-folders as mail arrives.

I have server-side rules for filtering messages into particular folders under my inbox. IF something comes into my inbox, I get notified almost instantly. If something goes into a sub-folder I have to wait 10 or 15 mins before it shows up in Mail (or Entourage)

That does sound like a tricky problem. The only mail application that I've heard of that powerusers actually really like is MailSmith. It's put out by the people who make BBEdit. If Mail won't do what you need it to, you might give MailSmith a try. The only thing is I don't think it does IMAP. I think it only does POP. Haven't looked at it in a while though. This might have changed.
