- Jan 16, 2013i want to plan a backup postfix server for minimizing the downtime. i
have read about MX record entry to use as backup server . but this if
for pure postfix only in my case i will be running round cube, dovecot
for IMAP storage. how is that possible that i just have to change the
DNS entry and people start accessing same settings same view of round
cube with in just 1 or 2 minutes of delay.
is there anyone can help me? DRBD is kinda complex. just for your
knowledge i am using local hard drive as storage not external storage.
