[Dovecot] DC testing observation and a question

[Stewart Dean]

I have been running a test DC IMAP server to evaluate the new release 
before migrating from 1.0.15 to 1.1.8.  The test server access all the 
INBOX and homedir folder filesystems through NFS imports.
The index file filesystem is local on both the production server and the 
test one..  This is messy in that when I ask some one tests using the 
test sever, the index has to be created or re-gennned, since the local 
index either doesn't exist or is several months old (from the last time 
a prospective upgrade was tested) and thus doesn't reflect data on the 
production DC IMAP server.

1) Watching the syslog maillog has been intriguing...different IMAP 
client show widely differently use patterns.
a) Users running TBird and Seamonkey have 2-5 imap sessions (ps -aef | 
grep <userid>) *but* very little syslog activity...sparse occasional 
logins and disconnects
b) Users running Exchange have only 1 imap sessions *but* every 5 
minutes will generate login and disconnect messages (in and out in the 
space of a second) for each folders.  So for a user with 22 folders, 
there will be 44 syslog messages in the maillog every 5 minutes.
Just curious....any thought as to which is more efficient and by how much?

2) When I try to switch a MacMail client over, it sees the new mail, but 
not the old mail in the INBOX.  How do I  force re-indexing on the test 
server?
