Finally managed to sync an outlook client to dovecot.
Looks like it's working.
Questions though ; :

What are the limits? Number of Folders ?
Number of mails per folder ?

E.g. for a client of mine, I know that she uses about
5Gb of data at the moment (and counting).
Now, this same outlook client consists of the following :

1. about thirty (30) folders ranging from 1000 messages per
folder to 100 messages per folder

2. A "Sent Items" folder with about 4,000 messages (and counting)

3. A "Deleted Items" folder with about 5,500 messages (and counting)

System, now, is a CentOS 5.5 32-bit on an hp/compaq dl360 (G3) with
RAID1 76,3Gb Disks UW320 and four (4Gb) of RAM

Output of "dovecot -n" :

# 1.2.16: /etc/dovecot/dovecot.conf

    args: uid=vmail gid=vmail home=/home/vmail/%u

Any answer would be greatly appreciated since I am trying to 
know the systems' limits.

Thank you kindly all,
