Thank you for your prompt reply and timely help. I will try to be very
explanative in describing my situation. I will begin first with answering
the questions you asked;
1) how are the messages storred on the old server, which storage
backend do you use, maybe Maildir?
Yes, Maildir. Dovecot version is 2.1.7.
Virtual users are authenticated by mysql backend. Login is plain login.
2) the storage backend on the new server?
Maildir. Dovecot Version 2.2.9. Mysql virtual users
authentication. Plain login
3) do you care about the message UIDs?
I Would like to preserve the UIDs as much as possible. However, the most
important thing is for the users to have access to their old emails.
4) How many users do you have (approx.) and can you access the user's
mailboxes via IMAP, e.g. using a master user or do you know their password
or can you switch to a known password during migration of one particular
user?
I have about 50 total users. I can access their mailboxes via imap but I
don't have their password handy. Mysql database with the userdata and
passwords was imported into the new new server so, the users can get
authenticated into the new server with the old server password.
5) Did you've changed namespaces?
No. I did not change namespaces.
- From your first post I figure that the basic mail server functionality of
the new server is working, most importantly login, message delivery and
retrieval.
Yes, the new server is functional and all the users are able to log in, view
delivered messages and retrieve the messages into their mail clients.
However, they cannot view any old messages or retrieve any old messages.
Here is the dovecot.conf of the old mail server;
protocols = imap pop3
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/var/vmail/%d/%n
mail_privileged_group = mail
first_valid_uid = 6060
ssl_cert= </etc/ssl/certs/dovecot.pem
ssl_key =< /etc/ssl/private/dovecot.pem
#ssl_ca = </etc/ssl/certs/gd_bundle.crt
ssl = yes
#ssl_cert = </etc/postfix/ssl/smtpd.crt
#ssl_key = </etc/postfix/ssl/smtpd.key
protocol imap {
mail_plugins = autocreate quota imap_quota
}
protocol pop3 {

mail_plugins = quota

you post very little information:
1) how are the messages storred on the old server, which storage backend do
you use, maybe Maildir?
2) the storage backend on the new server?
3) do you care about the message UIDs?
4) How many users do you have (approx.) and can you access the user's
mailboxes via IMAP, e.g. using a master user or do you know their password
or can you switch to a known password during migration of one particular
user?
5) Did you've changed namespaces?
- From your first post I figure that the basic mail server functionality of
the new server is working, most importantly login, message delivery and
retrieval.
I have attached both the old and new servers configuration files as .txt
attachments.
