<p>Hi,</p>
<p>I have two IMAP/LMTP Dovecot server in replica (version 2.3.4.1)
both connected through an IPsec tunnel, I use LDAP/AD for <i>userdb,
</i>all seems to be working.</p>
<p>I have a question: if I switch my Thunderbird/Outlook client to
use the other server I have to download again all the emails,
about 10 GB.</p>
<p>Is there any way to avoid this? Do I have to download again all
the folders every time I switch from node A to node B on my
client?</p>
<p>Thanks!</p>
<p>Regards<br>
</p>
