Email Server High Availability
Hello,
We are planning to setup a Email server with High Availability for email services so that if SMTP/POP/IMAP goes down on one server, the services switch to second server.
We are planning to use a Linux machines from a hosting provider and will do it using DNS with multiple MX records with round robin.
Now i have couple of queries regarding this setup :- - Is this possible to have a same domain name to bind with 2 IPs i.e xyz.com point to 1.1.1.1 on one server and xyz.com point to 2.2.2.2 on second server.
- How can we setup MX records for each server on DNS for email failover.
- As we have a separate servers for this setup that means data related to email would be reside on separate server (because they have separate HDD), so in case 1st server goes down and it switch to second server, will i skipped my email which was received on 1st server before it goes down as my email client will receive them on certain period of time.
Please let me know if above is a valid query.

NAME
Email::Sender::Failure - a report of failure from an email sending transport
VERSION
version 0.110005
ATTRIBUTES
message
This method returns the failure message, which should describe the failure. Failures stringify to this message.
code
This returns the numeric code of the failure, if any. This is mostly useful for network protocol transports like SMTP. This may be
undefined.
recipients
This returns a list (or, in scalar context, an arrayref) of addresses to which the email could not be sent.
METHODS
throw
This method can be used to instantiate and throw an Email::Sender::Failure object at once.
Email::Sender::Failure->throw(\%arg);
Instead of a hashref of args, you can pass a single string argument which will be used as the "message" of the new failure.
