Client host rejected: cannot find your hostname, [196.xxx.xx.xx] (in reply

it is on your ubuntu. most
it is on your ubuntu.
most probably, your server cannot resolve hostnames.

Problem at ISP
Seems like the problem was with my ISP.
I have a router with 5 Static IP's, 3 ip's pointed to internal mail servers, with some domains.
I had to ask my ISP to setup reversed DNS for the domains on these 3 ip's.
The mail is going out now with no problem.
It seems like some mail servers look for the reverse DNS before excepting mail, to stop people in sending spam.
