hi
i need to change the primary ip of my production qmailtoaster server
without any downtime / interruption of my email service.
i added one of the ips to the network card
i can get pop,imap and submission port connection on the new ip.
my problem is that currently the smtp run file is configure such that the
smtp is bound to my primary ip address.
how do i make qmail smtp listen on all ips on the network card so that
even during dns propagation there is no email service problems ?
is there is harm in doing the above ?
qmail-smtp should listen on all ips by default, try
lsof -i :25 | grep LISTEN
and you should see something like this:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
tcpserver 5263 vpopmail 3u IPv4 1188438534 0t0 TCP *:smtp
(LISTEN)
Ciao
