[Dovecot] Sync of read message status between squirrelmail and outlook express

Hi,

We have a Linux email server running CentOS 4.4.

I have a scenario here.

The users here use a mixture of outlook express and squirrel mail as their email client. The users download their mail into outlook express via pop3 but the have configured outlook express to leave a copy on the server for 7 days.

1. After downloading the mail into outlook express the users would read the mail and the mail would be set as 'READ' in outlook express.
2. Is there a way to configure dovecot so that the 'READ' status in outlook express is reflected on the message still stored on the server as well. Cause when they access via squirrel mail the message is still mark as 'UNREAD'.

Any suggestions is very much appreciated.

Thanks in advance.
