Add mx record to all domains..

write a perl script is probably the easiest.

 

me to have same problem
i have to add a second MX in 3500 domains
i don't find nothing

 

To make one time changes to several files, I just download them and use a good search/replace program to make the changes, then upload.

CuteHTML Pro and Note Tab Pro are both good for this.

I would open, modify, and close, 300 at a time and could do 3500 in less than an hour.

That's how I made changes when I switched servers once.

I could probably write a script to make the changes, but since there are a variety of changes that are sometimes done, it would mean several different scripts for the different types of changes, so it's just as quick to use a search/replace program, for me anyway.
