You said you have huge mailboxes - even replicating only one mailbox
can maxing out your line, because that's the nature of tcp/ip.<br>
The more data you have to transmit the longer your line will be
full.<br>
Depending how you have your VPN tunnel build you might be able to
limit the bandwidth on the tunnel endpoint if that's a separate
firewall/router/.. or you can do rate limiting with iptables as
well.<br>

<p>Hi all,</p>
<p>I have two IMAP/LMTP Dovecot server in replica (version
2.3.4.1) for testing purposes, both connected through an IPsec
tunnel, I use LDAP/AD for <i>userdb, </i>all seems to work
fine.<br>
</p>
<p>Now I would like to go in production where at the moment I have
only one server active and setup the replica too ... but! I need
to know how I can exclude all the users from replication
(help/examples appreciated!) and doing replication one user at a
time, in order to not saturate bandwidth on the IPsec tunnel.</p>
<p>I read <a moz-do-not-send="true"
href="https://wiki.dovecot.org/Replication">https://wiki.dovecot.org/Replication</a>:</p>
<p class="line862">"Since v2.3.1 you can disable replication for a
user by providing 'noreplicate' <a
href="https://wiki.dovecot.org/UserDatabase/ExtraFields"
moz-do-not-send="true">user database field</a>. Another way to
disable replication for some users is to return mail_replica
field from userdb for users you want to replicate."</p>
<p class="line862">but I can't figure out how to do it.<br>
<span class="anchor" id="line-12"></span><span class="anchor"
id="line-13"></span></p>
<p>One last question: since I have to deal with huge mailboxes, if
prior to activate replication I do an rsync between the two
Dovecot filesystems, does the replication will work?</p>
<p>Thanks in advance!</p>
<p>Cheers<br>
