HI All,
I am planning to configure backup MX for primary MX. i have few queries..
All email id's in primary MX need to be same in secondary MX?
yes. and all checks done on the primary should be done on the secondary
as well.
also, if the secondary passes mail to the primary, then the latter must
not reject it (because that would generate backscatter). you thus need
to deal with such mail.
finally, the secondary will attract a lot of spam (even if the primary
is up). you've been warned...
Is it possible to configure separate email clients to receive and send for both
mail server's, in case primary MX is down?
you seem confused...
an MX is for receiving mail from the Internet. this has nothing to do
with mail clients of your.
for your mail clients:
- for reading mail, refer top the documentation of your POP3 or IMAP
server. postfix doesn't do any of these.
- for submitting mail, set up submission MTAs. but you need an external
high availability solution because an email client will only try one MTA.
Please send suggestion's or URL to know more about this.
Thanks and Regards,
Ramesh
