[webmin-l] Setting up Usemin adn dovecot with maildir folders

[Richard C. <rch...@aa...>]

Hi,

I have an old mail server which uses mbox type mail folders. I presume 
this is why simple actions (like moving email to trash or to sent) are 
painfully slow. I am trying to set up a new server which I would like to 
use maildir - in the hope that this is a faster option for most things. 
My intention is to use postfix (because I think it will be simpler to 
configure and maintain than sendmail), dovecot for imap clients and 
usemin and/or squirrelmail for web based access.

I think I have postfix working - and have just installed usemin. I 
installed usemin before starting dovecot because dovecot looks like it 
will auto-detect the folders created by usemin. It appears to me that 
usemin is defaulting to mbox type folders. In particular the sent folder 
displays as type "file" at ~/mail/sentmail.  How were the "system" 
folders created? Can they also be created as maildir folders? There is 
no "Add Folder of Type:" option in usemin which looks like a maildir folder.

How do I persuade Usemin and/or dovecot  to create maildir type mail 
folders for all current and future users, and for both system (trash, 
sent. ...) and user defined mail folders.

I hope to be able to use an imap client (Thunderbird or maybe usemin?) 
to copy all the existing mail folders from the old server to the new 
server. There are only a small number of users on the old server but 
quite large mail folder trees for each user - so doing it one user at a 
time is not a huge problem. I would prefer not to have to do it one 
folder at a time. Are there any pitfalls that I need to be aware of?

Any suggestions for better ways to skin this cat...?

Thanks for the help.

Richard.
