Here is what I am now doing to fight problems with DNS servers going down.

 

I have installed DNS on the Imail server. It has no zones and answers queries only from Imail and Declude. I have set Imail DNS server to 127.0.0.1. I have then configured 4 forwarders in the DNS server properties.

 

Now, Imail and Declude ALWAYS find the local DNS server, and that server always has a pool of servers to forward to.

Aha. Secondary DNS that Declude was pointed to (BIND 9.2.2) had died, and the daemon that watches it to restart it, wasn't. Thanks, Bill.

I have not noticed an increase this weekend, myself, but maybe others have.
Is it mainly your DNS based tests that are failing or is it pretty much all
tests across the board?  If it's your DNS tests that are failing, check to
see if the DNS server that IMail is configured to use is working and
responding to queries (or, if you have a name server defined in your
Global.cfg file, check that one).

What do you see in your log file, are there any errors being reported?
