[dovecot] Apple's Mail.app

[Scott A.McIntyre]

Hi,

I solved the OSX Authentication issue; I'm now reliably able to get 
authenticated using the Password Server with PAM with:

# login: auth account password session
auth       required       pam_nologin.so
auth       sufficient     pam_securityserver.so
auth       sufficient     pam_unix.so
auth       required       pam_deny.so
account    required       pam_permit.so
password   required       pam_deny.so
session    required       pam_permit.so


As the /etc/pam.d/imap

Anyway -- new problem.  With Apple's Mail.app and how it wants to 
download messages into it's cache, I've found that there's a 
problematic interaction between Dovecot and Mail.app -- but pinning 
down exactly what and where is proving to be a hassle.

I was running Courier-Imap with Mail.app, and that worked without 
incident (however, the courier-imap server was on Linux, not OSX 
Server, that will not work (yet) with osx-server).

If I use Entourage and Dovecot, it works fine.

The primary symptom is that as it downloads messages Mail.app just 
hangs; no response, the session just freezes.  Usually it's when the 
status bar is saying something akin to "Caching 9 of 506" at which 
point it stops.  The number varies, but it's always in the first couple 
of dozen.  Messages are small, so it's not that it's hanging on a large 
mail download.  I eventually have to forcibly kill Mail.app.

The log says nothing of use:

dovecot: Mar 07 17:31:23 Info: Dovecot starting up
imap-login: Mar 07 16:32:50 Info: Login: scott [194.109.29.21]
imap-login: Mar 07 16:33:46 Info: Login: scott [194.109.29.21]
imap-login: Mar 07 16:35:38 Info: Login: scott [194.109.29.21]


But perhaps there's a more verbose option somewhere.

Thoughts?
