<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for the replies, the problem with shutting down all mail is that will also stop mail to our dovecot Mail platform, which is not going to be offline for any migration... So 90% of clients will not receive mail so that I can clean
up the dbmail server (that has 10% of clients on it).<o:p></o:p></p>

<div>
<p class="MsoNormal">A fun tip, the dbmail server uses innodb... I have one table which is 650GB.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<p class="MsoNormal">Its going to take about 2 hours to migrate the DB over to new MySQL server, after which the table is 70GB. I was just concerned about mail bouncing during that time because it could not deliver to the dbmail server. I might check out postfix
retry time..<o:p></o:p></p>

<p class="MsoNormal">If you shut down MailScanner and Postfix, obviously no email will be processed. You can also shut down MailScanner and make sure Postfix is started and it will accept the email and hold it in /var/spool/postfix/hold until you start MailScanner
again. <o:p></o:p></p>
