Greetings
We recently installed Squirrelmail onto a customer's mail server.
The setup is this:
FC9
php-5.1.6-3.7.fc6
httpd-2.2.3-5
dovecot-1.0.3-6.fc6
SquirrelMail version 1.4.15
As well as the normal users account, we also have an account called (for the
sake of brevity) "Plans" (think "Customers"). Below this account is a
separate folder for each Plan. It looks like this:
Plan-1
Plan-2
......
......
Plan-9999
Each of the users has responsibility for a subset of the Plans, but
everybody also needs access to all the Plans folders.
Consequently, an end users folder structure will look like this:
Inbox
Trash
My Plans
Plan-27
Plan-101
Personal Files
Work Files
More Folder
...........
More Folders
All Plans
Plan-1
Plan-2
Plan-3
.....
.....
Plan-999
Other Folders
This has been done so that they can collapse "All Plans" and deal just with
"My Plans" but they can (of needed) get access to all the plans (customers)
emails.
The "All Plans" is a separate IMAP account that everyone is subscribed to.
The "My Plans is a just folder that contains symbolic links back to the
actual folders (from All Plans).
symlinks to implement shared mail folders? Is this the official
recommendation from dovecot on how to implement this? If dovecot
dumps any of its own data (subscription/other) files into mail
folders, then this kind of symlinking is bound to break IMO. You need
to take this whole design to the dovecot community and make sure it
really will work before you try to figure out if it will work via
webmail. If you insist on solving a server problem using a client,
though, turn up your IMAP logging verbosity or sniff the connection
between webmail and IMAP to see the commands and responses and errors
dovecot is throwing.
Dovecot does not recommend using symlinks. I have managed dovecot servers
Since Redhat v8 and have never recommended or have it recommended to me to
ever use symlinks. On the contrary, using symlinks can, and apparently
does, cause undesirable affects.
Don't use symlinks unless you can verify and quantify the potentialities
as you encounter them. Too many moving parts? Start over and do it 'by the
book'
My 2 pence.

Whilst I do not doubt your good intentions and experience, and have no
desire to get into a tussle over this, according to Tino Sirainen just
a few months ago:
Some future Dovecot version will hopefully have a better support for
shared mailboxes, but for now symlinks are probably the best you can do.
