I have few domains on the server. Some part of them use my server for send emails but few have configured external mail service like Google. I need to disable using my mail service by colonel.com.pl on my server. There need to be only google, nothing more but other domains need to use my mail service. -- *Pozdrawiam / Best Regards* *Piotr Bracha*
