I changed ownership of the files and that worked better.
I am not paranoid, but want to do things right, considering the
passwords in plaintext inside the users .fetchmailrc files?

I'm sorry, bad english, I meant happend at the same time. :)
I too said that primes would ensure they only would poll at the same
time every prime1 * prime2, but non primes will do if they are good
selected, I know what I want to say, but I don't know the english words
for it. :(
9 and 16 would be ok, but not 9 and 15.
But sticking to primes seems like the way to go.... as long as the not
are 7 all of them :)
one more/other thing, i have an old 466mhz width 384MB ram I will setup
as a server, I consider centos and debian, which one would you
