Hi Marc,

thanks for replying, I would like to archive e-mail older than 5 years on a second storage, it seems like the namespace with a new mail_location that you suggested could be good for me, but then I will need the auto-archiving script that move mails older than 5 years to the archive namespace.

A question: how can I configure client like Thunderbird to access that archive namespace so that users can still access their old mails?

Please could you give me some suggestion on how to do that?

Thanks for your time!

Regards

I am not really sure what you are trying to realize with this ldap modification. But afaik you have just one mail_location= configuration per user and that is it. If you want to archive email on 2nd storage you can either use this ALT= storage location or create a namespace, and configure this namespace with a new mail_location. The latter I have done indeed as archive, and after every first quarter I am running an auto-archiving script that moves emails from the usual inbox and send folders to the archive namespace.

I have an MTA configured with Postfix that deliver email to an IMAP/LMTP
Dovecot server version 2.3.4.1 configured to bind LDAP/AD for users.

I would like to configure Dovecot to create another mailbox to archive
mails of users to a separated NFS mount.

Here is my dovecot-ldap.conf:

[...]

ldap_version=3
auth_bind = yes
dn = XXX
dnpass = XXX
scope = subtree
user_attrs = sAMAccountName=home=/mnt/mail-storage-
dev/%$,=uid=501,=gid=501
pass_attrs = sAMAccountName=user
user_filter = (&(objectclass=person)(samaccountname=%n))
pass_filter= (&(objectclass=person)(samaccountname=%n))


[...]


I think I will add another conf file, let's say dovecot-ldap-
archive.conf using "url" as LDAP/AD filed to distinguish from normal
users:

[...]

ldap_version=3
auth_bind = yes
dn = XXX
dnpass = XXX
scope = subtree
user_attrs = url=home=/mnt/mail-storage-archive/%$,=uid=501,=gid=501
pass_attrs = url=user
user_filter = (&(objectclass=person)(url=%n))
pass_filter= (&(objectclass=person)(url=%n))


[...]

I then added to "test" user a "url" filed into Active Directory named
test-archive, but it's not working, when I bind Dovecot with:

doveadm user test-archive

I receive:

field    value
userdb lookup: user test-archive doesn't exist


With test user it works:

doveadm user test
field    value
uid    501
gid    501
home    /mnt/mail-storage-dev/test
mail    maildir:~/Maildir:INDEX=/var/indexes/test


What I'm doing wrong?


Thanks in advance!
