[Dovecot] Problem with Courier POP3 Migration to dovecot POP3

[Ashraf]

Hi Timo/all
   Help me please, i am in the process of migrating courier to dovecot
1.1.14. I want to do migration as users loging so i am using this script *
http://www.dovecot.org/tools/courier-dovecot-migrate.pl *,
When i do use post-logging script to migrate* POP3*, its downloading
messages again (*Duplicating messages)* , as some of our users prefer to
leave messages on server. If i run the script manually on particular users
home directory and try to download it *still duplicating messages, *as its
creating whole new set of dovecot files.
*
*
About my environment

 -- MailDir's stored in NFS location
 -- User Authenticated using MySQL


 my dovecot.conf looks like

base_dir = /var/run/dovecot/
protocols = imap pop3
listen = *, [::]

ssl_disable = yes
login_process_per_connection = no

protocol imap {
}

protocol pop3 {
  *mail_executable = /usr/libexec/dovecot/postpop3.sh*
  mail_max_userip_connections = 10
  pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
}
auth_verbose = yes
auth_debug = yes
auth default {
  mechanisms = plain
  passdb sql {
args = /etc/dovecot-mysql.conf
  }
  userdb sql {
args = /etc/dovecot-mysql.conf
  }
  user = root
}

dict {

$ cat /usr/libexec/dovecot/postpop3.sh

#!/bin/sh
# WARNING: Be sure to use mail_drop_priv_before_exec=yes,
# otherwise the files are created as root!
/usr/libexec/dovecot/courier-dovecot-migrate.pl --quiet --to-dovecot
--recursive --convert  ${HOME}
# This is for pop3

Once the script is executed its executing the binary as a last step.
Reference http://wiki.dovecot.org/Migration/Courier

 You can also convert each user as they log in for the first time, using
PostLoginScripting <http://wiki.dovecot.org/PostLoginScripting> with a
script something like:

#!/bin/sh
# WARNING: Be sure to use mail_drop_priv_before_exec=yes,
# otherwise the files are created as root!

courier-dovecot-migrate.pl --quiet --to-dovecot --convert ~/Maildir
# This is for imap, create a similar script for pop3 too
exec /usr/local/libexec/dovecot/imap

in place of ~/Maildir i want to pass the home directory of users which is
passed as mail variable (Query from MySql).

Appreciate your response.

[Dovecot] Help please- Post - Login Script--- Migration

[Ashraf]

Hi all
  I am in the process of migrating Courier to Dovecot, am using
courier-dovecot-migrate.plit
works fine. I want to migrate each user as they login using post-login
script (As i have huge no of users). We are using NFS storage,  users are
authenticated using mysql, User home directories as passed using variable
mail ( usign mysql query).

   I am trying to execute postlogin script which does the conversion but
unable to pass the user home directories .


--*/etc/dovecot.conf

mail_executable = /usr/libexec/dovecot/postloginscript.sh %h
---*
%h   for home directory.


---*postloginscript.sh

#!/bin/sh
/usr/libexec/dovecot/courier-dovecot-migrate.pl --quiet --to-dovecot
--recursive --convert $1
# This is for  pop3
exec /usr/libexec/dovecot/pop3
*


When i pass %h as argument its creating  "%h" directory and writing
dovecot-uidlist and rest the files in %h directory. Its not interpreting the
%h and not passing the home directory. Its just passing as it is.

Hope i am clear in articulating my problem. Please help.
