How to convert emails sent in webmin to squirrelmail "Sent" folder

Hi all,
I've done converting a dedicated postfix email server that uses pam authentication to a multi-domain virtual host (still postfix) server. The new system is a fresh installation of OpenSuSE 11.

I've done converting accounts and mboxes to Maildirs.

The old system uses usermin and I have to use squirrelmail for the new system because usermin only suports system accounts and I am using mysql as the user and password backend for the new system. Now the problem arises as I have not found out a way to transfer the emails sent by usermin users to their new squirrelmail Sent folder. I can see there's a .usermin folder under each system user's home folder in the old system and some information such as addressbooks stored in clear text format which I can do the conversion with no problem but with email sent I have no clue.

Regards

Actually I found the answer today, the sent emails of each user are stored under ~/mail/sentmail in mbox format. All I need to do is to use the mbox to maildir conversion script (perfect_maildir.pl is the one I am using) in a for loop and save the converted emails to each users maildir under a subfolder .Sent which should be added to the subscriptions file as well. Here's the script
( the sentmails are compressed individually with the format username.tgz and sent to the new email server through scp )

Code:

---

#!/bin/bash
BASE=/home/vmail/myclientsdomain.com
cd /var/tmp
mkdir -p sm/{tmp,working,done}
for u in *.tgz; do
  [ "`ls -A working`" ] && rm -rf working/*
  [ "`ls -A tmp`" ] && rm -rf tmp/*
  #get username
  user=${u%.tgz}
  #extract file
  tar -xzf $u -C working
  mkdir tmp/{new,cur,tmp}
  /usr/local/bin/perfect_maildir.pl tmp/ < working/$user/mail/sentmail
  chown -R vmail:vmail tmp
  chmod -R 700 tmp
  #create .Sent folder and subscribe to it if it doesn't exist
  [ -d $BASE/$user/.Sent ] || {
      mkdir -p $BASE/$user/.Sent/{new,cur,tmp}
      chown -R vmail:vmail $BASE/$user/.Sent
      chmod 700 $BASE/$user/.Sent
      sub=$BASE/$user/subscriptions
      touch $sub
      grep -q "Sent" $sub || echo "Sent" >> $sub
      chown vmail:vmail $sub
      chmod 600 $sub
  }
  find tmp -type f -exec cp -p {} $BASE/$user/.Sent/cur \;
  mv $u done/
  echo "done for user $user"
done
