note that spammers and viruses STILL target secondary/backup MX
servers....and 99.9999% of the time your customers only THINK they need
a backup MX (mostly because they're relying on obsolete advice from over
a decade ago when backup MX servers weren't such a bad idea). these days
they are rarely needed, and generally cause a lot more trouble than they
I'd be curious as to any details on how things had changed in the past
What is listed in our DNS as a backup MX is currently not accepting smtp
connections, as we don't have recipient maps or any spam filtering there
and this causes problems....
On our TODOs list is getting spam/virus protection on the backup MX.
