<div>I have had fairly good luck with
imapsync.<br>
I have used it to clone millions of emails but it is not the
worlds most efficient way of doing it but since this is usually a
one time operation toughing out the run-time over the coding and
testing of something more optimal is usually not worth it.<div><div class="h5"><br></div></div></div></div></blockquote><br></div>I'm familiar with imapsync. I've done in the past a few migrations of small servers (less than 500 mailboxes) with that tool, it performed well in that scenarios. The drawbacks were the time spent in that job and the necessity of knowing both original and destination passwords. <br><br></div><div class="gmail_extra">I can reset the original password, but I can't do that with the destination passwords. They're the users password for active directory accounts. That's the reason I thought about using an lmtp approach. <br><br></div><div class="gmail_extra">Andrés <br></div><div class="gmail_extra"><br></div></div>
